+-   keep everyone in the loop without them feeling like they&rsquo;re overloaded
+
+Everyone:
+
+-   [ ] Call for participation (speakers and volunteers)
+-   [ ] Reminder about CFP
+-   [ ] Last call
+
+Speakers:
+
+-   [ ] Send all speakers backstage access and upload instructions
+-   [ ] Send all speakers check-in instructions
+
+Volunteers:
+
+-   [ ] Send captioning volunteers the backstage info
+-   [ ] Send past captioning volunteers an invitation to participate - ask when there&rsquo;s a lot of load
+-   [ ] Ask for help with audio processing

+
+This table makes it easier to move the slider depending on who wants
+to volunteer and how much we can get done. At some point, we&rsquo;ll figure
+out how to track our current status so we know what we need to
+scramble to do in order to get the conference off the ground. **bold**
+is our current goal. Feel free to volunteer for anything that
+interests you!

+
+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
+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&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.
