+# Call for participation
+
+What have you found exciting about [Emacs](https://www.gnu.org/software/emacs/) lately? Have you figured out a good workflow? Used Emacs for something interesting? Come share what you've been learning at EmacsConf 2025 and meet other enthusiasts along the way! All backgrounds and all levels of experience are welcome. Emacs isn't just a text editor, it's a way of life!
+
+[EmacsConf 2025](https://emacsconf.org/2025/) will be a virtual conference on **December 6 and 7, 2025 (Sat-Sun, 9AM-5PM UTC-5 America/Toronto, which is the same as 2PM-10PM UTC)**. We hope to get your talk proposal by ****Friday, September 19, 2025.****
+
+If there are similar proposals, we'll work with people so that the talks can cover different facets.
+
+
+# Talk formats
+
+Ideally, talks will be prerecorded so that you can script and edit them as tightly as you want, and so that they can be captioned for accessibility. Here are the talk options:
+
+- **5-10 minute lightning talk:** just the essentials! If you can squeeze your prerecorded talk into 5-10 minutes by focusing on the essentials (not by talking super quickly!), we might be able to repeat it during the conference in order to fill gaps.
+- **20-minute talk:** short enough to keep people's attention, long enough to get into some details.
+
+There will be time for questions and answers after your talk, so you don't need to include that in your talk timing. Just like in previous EmacsConf, you can answer questions via a live video conference, IRC ([Internet Relay Chat](https://chat.emacsconf.org)), the Etherpad (a web-based collaborative document), the wiki, or email (your choice). The stream will move on to the next talk at the scheduled time, but interested people can keep hanging out with you for a longer conversation.
+
+If you are not available during the conference itself but you have a neat idea that you'd like to share, please propose it anyway! You can always handle questions after the conference, and we might even be able to coordinate with other Emacs meetups for events in other time zones.
+
+We may have time for a few longer sessions. If you'd like to be considered for a longer time slot, please include an outline for the extra time in addition to your 20-minute proposal. Other session formats such as tutorials, workshops, and hangouts are welcome as well.
+
+
+# Submitting your proposal
+
+[Send us your idea](https://emacsconf.org/2025/submit/) as soon as you can, so that you can have more time
+to work on your talk. (Proposal deadline: ****Friday, September 19, 2025****)
+
+If you need help, you can email us publicly at [emacsconf-org@gnu.org](mailto:emacsconf-org@gnu.org)
+or privately at [emacsconf-org-private@gnu.org](mailto:emacsconf-org-private@gnu.org). You can also come and
+say hi to us on our IRC channel `#emacsconf` on `irc.libera.chat`
+using [your favourite IRC client](ircs://irc.libera.chat:6697/emacsconf), or by visiting [chat.emacsconf.org](https://chat.emacsconf.org) in
+your web browser.
+
+
+# Know someone who might have something to share?
+
+All kinds of people use Emacs for all kinds of things. We'd love it
+if EmacsConf 2025 could highlight interesting perspectives and reflect
+the diversity of our community. If you know someone who might have a
+good idea for a talk, please reach out to them and encourage them to
+submit a proposal. Many people (especially from underrepresented
+groups such as women, people of colour, non-developers, etc.) might
+not consider themselves proficient enough to share their thoughts.
+If you let them know that you value their knowledge and experiences,
+and maybe even suggest something that you think others would like to
+hear about, they may realize that they do have something worth sharing
+and that we would love to hear from them.
+
+
+# Want to volunteer?
+
+If you would like to help with the conference (planning the sessions,
+reviewing proposals, helping with infrastructure, making sessions
+more accessible, editing video transcripts, checking in speakers,
+reading questions out loud, organizing notes, etc.), please see our
+[volunteer](https://emacsconf.org/volunteer/) page. Volunteers get early access to talks and learn lots
+of things along the way. We'd really appreciate your help in making
+EmacsConf 2025 the best one so far!
+
+
+# Commitment to freedom
+
+We remain fully committed to freedom. You'll be able to participate
+in EmacsConf using [free/libre software](https://www.gnu.org/philosophy/free-sw.html), and we use free/libre software
+to organize and run the conference. You can find some notes about our
+setup and process at <https://emacsconf.org/infra/>.

+
+* COMMENT How to export this file :noexport:
+
+The =ircs= link type is not part of standard Org Mode, so Org will
+throw an error if you try to export this file.
+
+To work around that, you can use something along the lines of the
+Emacs Lisp code below by either adding it to your init file, or by
+putting the point in the code block and hitting =C-c C-v e= (that is,
+hold Ctrl, then hit c followed by v, then release Ctrl, and hit e) to
+evaluate the code, working around the issue only for the current
+session.
+
+#+begin_src emacs-lisp :results silent
+(org-link-set-parameters
+ "ircs"
+ :export
+ (lambda (link description format)
+ "Export an ircs link.
+See `org-link-parameters' for details about LINK, DESCRIPTION and
+FORMAT."
+ (let ((desc (or description link)))
+ (pcase format
+ (`html (format "<a href=\"ircs:%s\">%s</a>" link desc))
+ (`md (format "[%s](ircs:%s)" desc link))
+ (_ nil)))))
+#+end_src
+
+Other CFPs we can borrow ideas from:
+
+- https://debconf23.debconf.org/cfp/ - includes early submission timeline
+- https://fosdem.org/2023/news/2022-11-13-call-for-presentations/ - mentions upload date, license
+- https://www.fsf.org/blogs/community/libreplanet-2023-will-be-held-march-18-19-cfs-extended-to-november-23

+
+Welcome to EmacsConf 2025, where we have fun
+exploring how much we can do with a text editor.
+It&rsquo;s hard to give a general overview
+of all the cool talks today and tomorrow,
+so you can flip through the talks
+and see what sparks your interests.
+Don&rsquo;t feel limited to one track or another.
+The best parts of EmacsConf are the conversations.
+The wiki has a page on how to watch and participate,
+and I&rsquo;ll give you a quick overview as well.
+You can watch both streams at live.emacsconf.org
+using free and open source software.
+Using a streaming media player like mpv
+seems to be the best way to watch in terms of performance
+but there are also web-based players
+just in case that&rsquo;s all you&rsquo;ve got.
+The schedule shows the General track on top
+and the Development track on the bottom,
+so you can see what else is going on.
+As you&rsquo;re watching the talks,
+you can refer to the schedule in another window.
+Hover over the boxes to see the times and titles,
+and click on the boxes in the schedule
+to jump to the talk&rsquo;s page for more details.
+You can also get the schedule as an iCalendar file
+or as an Org file in different time zones.
+Many talks will be followed by
+live Q&A web conferences with the speaker,
+which will be done in BigBlueButton or BBB.
+These are indicated with a solid border on the schedule
+and by Q&A: BBB on the schedule page.
+You can join the web conference room
+by clicking on the BBB link
+on the schedule page or the talk&rsquo;s webpage.
+Then you can ask your questions yourself when the Q&A starts.
+To improve performance, please keep your webcam off
+and stay muted until it&rsquo;s your turn to talk.
+If you don&rsquo;t like Javascript,
+you can still ask questions via IRC
+and the hosts can read them out for you.
+We&rsquo;re probably going to automatically switch
+between talks and Q&A sessions,
+so the transitions on the stream might be a little sudden.
+
+People in the BigBlueButton room
+can continue the conversation
+even after the talk moves off-stream.
+and you can also reach out to the speakers
+using the contact information on the talk page.
+
+Other talks will have Q&A via Etherpad or IRC,
+depending on what the speakers prefer.
+This is indicated in the schedule with a dashed border
+and on the schedule page as well.
+Some talks will have the Q&A after the event,
+so you can add your questions to their Etherpad
+or ask on IRC.
+We&rsquo;ll e-mail the speakers afterwards
+and update the talk pages when they answer.
+The schedule pages and track pages have quick shortcuts
+so that you can find out more about talks, open the Etherpads,
+and join the Q&A sessions. The watch page has more tips
+on how to make the most of Q&A.
+If you can, please add notes and ask questions
+in the Etherpad for the talk. That makes it easier
+for everyone to share their notes,
+and speakers and hosts can read the questions from there.
+We&rsquo;ll copy the notes to the talk pages afterwards.
+We have one pad for each talk,
+so you can follow the links to get to the next one
+or go back to the schedule and get the link from there.
+If you have general feedback about
+the conference itself, please put it in
+pad.emacsconf.org/2025 , which is linked on each pad.
+You can also use this as a general community message board
+for things like Help Wanted.
+Internet Relay Chat or IRC can be another great way
+to be part of lots of conversations.
+You can use chat.emacsconf.org to join the IRC channels
+through your web browser. The tabs on the left can help you
+switch between the different channels.
+There&rsquo;s #emacsconf-gen for the General track
+and #emacsconf-dev for the Development track.
+If you need to reach us, you can join #emacsconf-org
+or e-mail emacsconf-org-private@gnu.org.
+You can use #emacsconf for hallway conversations.
+Of course, you can join any of these channels
+with your favourite IRC client.
+You can connect to irc.libera.chat
+port 6697 with TLS.
+Once again, we&rsquo;re going to be streaming with open captions
+for most of the talks this year, thanks to our speakers and
+captioning volunteers. The captioned talks are indicated
+on the schedule, and with any luck, we&rsquo;ll be posting
+transcripts on talk pages shortly after the talks start.
+If you need additional accommodations,
+please let us know in #emacsconf-org
+and we&rsquo;ll see if we can make things happen.
+If something goes down, we&rsquo;ll update status.emacsconf.org.
+If it doesn&rsquo;t look like we&rsquo;ve noticed yet,
+please let us know in the #emacsconf-org IRC channel,
+where we will be quietly panicking.
+In all of these conversations, please keep in mind
+our guidelines for conduct. You can find them on the wiki,
+They basically boil down to: please be nice.
+If all goes well, the prerecorded talks and transcripts
+should be available from the talk pages
+shortly after they start playing,
+and we&rsquo;ll post the recordings of live talks
+and Q&A sessions within the next month or so.
+If you&rsquo;d like to get an update, you can subscribe to
+the emacsconf-discuss mailing list.
+All right, let&rsquo;s get going.
+Leo is hosting the general track,
+and Corwin hosting the development track.
+The other volunteers and I will run around mostly backstage,
+and you&rsquo;ll probably meet us in the closing remarks.
+That&rsquo;s also where we get to thank
+all the people and organizations
+who make EmacsConf possible.
+Thanks for coming to EmacsConf 2025.

+Please ask your questions in the recommended places

+
+Some talks will have the Q&A after the event,
+so you can add your questions to their Etherpad.
+We&rsquo;ll e-mail the speakers afterwards
+and update the talk pages when they answer.
+
+We&rsquo;re going to start Sunday morning
+with more IRC/Etherpad Q&A
+to try to get around
+some of the bandwidth issues
+that we noticed last year.
+
+The schedule pages and track pages have quick shortcuts
+so that you can find out more about talks, open the Etherpads,
+and join the Q&A sessions. The watch page has more tips
+on how to make the most of Q&A.
+If you can, please add notes and ask questions
+in the Etherpad for the talk. That makes it easier
+for everyone to share their notes,
+and speakers and hosts can read the questions from there.
+We&rsquo;ll copy the notes to the talk pages afterwards.
+We have one pad for each talk,
+so you can follow the links to get to the next one

+
+Welcome to EmacsConf 2025, where we have fun
+exploring how much we can do with a text editor.
+It's hard to give a general overview
+of all the cool talks today and tomorrow,
+so you can flip through the talks
+and see what sparks your interests.
+Don't feel limited to one track or another.
+The best parts of EmacsConf are the conversations.
+The wiki has a page on how to watch and participate,
+and I'll give you a quick overview as well.
+You can watch both streams at live.emacsconf.org
+using free and open source software.
+Using a streaming media player like mpv
+seems to be the best way to watch in terms of performance
+but there are also web-based players
+just in case that's all you've got.
+The schedule shows the General track on top
+and the Development track on the bottom,
+so you can see what else is going on.
+As you're watching the talks,
+you can refer to the schedule in another window.
+Hover over the boxes to see the times and titles,
+and click on the boxes in the schedule
+to jump to the talk's page for more details.
+You can also get the schedule as an iCalendar file
+or as an Org file in different time zones.
+Many talks will be followed by
+live Q&A web conferences with the speaker,
+which will be done in BigBlueButton or BBB.
+These are indicated with a solid border on the schedule
+and by Q&A: BBB on the schedule page.
+You can join the web conference room
+by clicking on the BBB link
+on the schedule page or the talk's webpage.
+Then you can ask your questions yourself when the Q&A starts.
+To improve performance, please keep your webcam off
+and stay muted until it's your turn to talk.
+If you don't like Javascript,
+you can still ask questions via IRC
+and the hosts can read them out for you.
+We're probably going to automatically switch
+between talks and Q&A sessions,
+so the transitions on the stream might be a little sudden.
+
+People in the BigBlueButton room
+can continue the conversation
+even after the talk moves off-stream.
+and you can also reach out to the speakers
+using the contact information on the talk page.
+
+Other talks will have Q&A via Etherpad or IRC,
+depending on what the speakers prefer.
+This is indicated in the schedule with a dashed border
+and on the schedule page as well.
+Some talks will have the Q&A after the event,
+so you can add your questions to their Etherpad
+or ask on IRC.
+We'll e-mail the speakers afterwards
+and update the talk pages when they answer.
+The schedule pages and track pages have quick shortcuts
+so that you can find out more about talks, open the Etherpads,
+and join the Q&A sessions. The watch page has more tips
+on how to make the most of Q&A.
+If you can, please add notes and ask questions
+in the Etherpad for the talk. That makes it easier
+for everyone to share their notes,
+and speakers and hosts can read the questions from there.
+We'll copy the notes to the talk pages afterwards.
+We have one pad for each talk,
+so you can follow the links to get to the next one
+or go back to the schedule and get the link from there.
+If you have general feedback about
+the conference itself, please put it in
+pad.emacsconf.org/2025 , which is linked on each pad.
+You can also use this as a general community message board
+for things like Help Wanted.
+Internet Relay Chat or IRC can be another great way
+to be part of lots of conversations.
+You can use chat.emacsconf.org to join the IRC channels
+through your web browser. The tabs on the left can help you
+switch between the different channels.
+There's #emacsconf-gen for the General track
+and #emacsconf-dev for the Development track.
+If you need to reach us, you can join #emacsconf-org
+or e-mail emacsconf-org-private@gnu.org.
+You can use #emacsconf for hallway conversations.
+Of course, you can join any of these channels
+with your favourite IRC client.
+You can connect to irc.libera.chat
+port 6697 with TLS.
+Once again, we're going to be streaming with open captions
+for most of the talks this year, thanks to our speakers and
+captioning volunteers. The captioned talks are indicated
+on the schedule, and with any luck, we'll be posting
+transcripts on talk pages shortly after the talks start.
+If you need additional accommodations,
+please let us know in #emacsconf-org
+and we'll see if we can make things happen.
+If something goes down, we'll update status.emacsconf.org.
+If it doesn't look like we've noticed yet,
+please let us know in the #emacsconf-org IRC channel,
+where we will be quietly panicking.
+In all of these conversations, please keep in mind
+our guidelines for conduct. You can find them on the wiki,
+They basically boil down to: please be nice.
+If all goes well, the prerecorded talks and transcripts
+should be available from the talk pages
+shortly after they start playing,
+and we'll post the recordings of live talks
+and Q&A sessions within the next month or so.
+If you'd like to get an update, you can subscribe to
+the emacsconf-discuss mailing list.
+All right, let's get going.
+Leo is hosting the general track,
+and Corwin hosting the development track.

+
+Welcome to the second day of EmacsConf 2025.
+The best parts of EmacsConf are the conversations.
+The wiki has a page on how to watch and participate,
+and I'll give you a quick overview as well.
+You can watch the stream at live.emacsconf.org
+using free and open source software.
+Using a streaming media player like mpv
+seems to be the best way to watch in terms of performance
+but there are also web-based players
+just in case that's all you've got.
+As you're watching the talks,
+you can refer to the schedule in another window.
+Hover over the boxes to see the times and titles,
+and click on the boxes in the schedule
+to jump to the talk's page for more details.
+You can also get the schedule as an iCalendar file
+or as an Org file in different time zones.
+
+Many talks will be followed by
+live Q&A web conferences with the speaker,
+which will be done in BigBlueButton or BBB.
+These are indicated with a solid border on the schedule
+and by Q&A: BBB on the schedule page.
+You can join the web conference room
+by clicking on the BBB link
+on the schedule page or the talk's webpage.
+Then you can ask your questions yourself when the Q&A starts.
+To improve performance, please keep your webcam off
+and stay muted until it's your turn to talk.
+If you don't like Javascript,
+you can still ask questions via IRC
+and the hosts can read them out for you.
+
+We're probably going to automatically switch
+between talks and Q&A sessions,
+so the transitions on the stream might be a little sudden,
+People in the BigBlueButton room
+can continue the conversation
+even after the talk moves off-stream,
+and you can also reach out to the speakers
+using the contact information on the talk page.
+
+Other talks will have Q&A via Etherpad or IRC,
+depending on what the speakers prefer.
+This is indicated in the schedule with a dashed border
+and on the schedule page as well.
+Please ask your questions in the recommended places
+so that the speakers can easily see them.
+
+Some talks will have the Q&A after the event,
+so you can add your questions to their Etherpad.
+We'll e-mail the speakers afterwards
+and update the talk pages when they answer.
+
+We're going to start Sunday morning
+with more IRC/Etherpad Q&A
+to try to get around
+some of the bandwidth issues
+that we noticed last year.
+
+The schedule pages and track pages have quick shortcuts
+so that you can find out more about talks, open the Etherpads,
+and join the Q&A sessions. The watch page has more tips
+on how to make the most of Q&A.
+If you can, please add notes and ask questions
+in the Etherpad for the talk. That makes it easier
+for everyone to share their notes,
+and speakers and hosts can read the questions from there.
+We'll copy the notes to the talk pages afterwards.
+We have one pad for each talk,
+so you can follow the links to get to the next one
+or go back to the schedule and get the link from there.
+If you have general feedback about
+the conference itself, please put it in
+pad.emacsconf.org/2025 , which is linked on each pad.
+You can also use this as a general community message board
+for things like Help Wanted.
+Internet Relay Chat or IRC can be another great way
+to be part of lots of conversations.
+You can use chat.emacsconf.org to join the IRC channels
+through your web browser. The tabs on the left can help you
+switch between the different channels.
+Most discussions will be in
+#emacsconf-gen for the General track.
+If you need to reach us, you can join #emacsconf-org
+or e-mail emacsconf-org-private@gnu.org.
+You can use #emacsconf for hallway conversations.
+Of course, you can join any of these channels
+with your favourite IRC client.
+You can connect to irc.libera.chat
+port 6697 with TLS.
+Once again, we're going to be streaming with open captions
+for most of the talks this year, thanks to our speakers and
+captioning volunteers. The captioned talks are indicated
+on the schedule, and with any luck, we'll be posting
+transcripts on talk pages shortly after the talks start.
+If you need additional accommodations,
+please let us know in #emacsconf-org
+and we'll see if we can make things happen.
+If something goes down, we'll update status.emacsconf.org.
+If it doesn't look like we've noticed yet,
+please let us know in the #emacsconf-org IRC channel,
+where we will be quietly panicking.
+In all of these conversations, please keep in mind
+our guidelines for conduct. You can find them on the wiki,
+They basically boil down to: please be nice.
+If all goes well, the prerecorded talks and transcripts
+should be available from the talk pages
+shortly after they start playing,
+and we'll post the recordings of live talks
+and Q&A sessions within the next month or so.
+If you'd like to get an update, you can subscribe to
+the emacsconf-discuss mailing list.
+All right, let's get going.
+Leo Vivier is hosting the general track again today.
+The other volunteers and I will run around mostly backstage,
+and you'll probably meet us in the closing remarks.
+That's also where we get to thank
+all the people and organizations
+who make EmacsConf even possible.
+Thanks for coming to EmacsConf 2025.
