+Thank you so much for being part of EmacsConf ${conf-year}! Hundreds of people
+enjoyed it, and I'm sure even more will come across the videos in the
+days to follow.
+Your prerecorded video is available on the talk page at ${url} , and
+we've added the questions and comments that we've collected from
+IRC/BBB/Etherpad. The recording of your Q&A session is also on the
+talk page.
+We've also uploaded your talk video to ToobNix (a PeerTube instance)
+at ${toobnix-url} and YouTube at ${youtube-url} . If you
+want to reupload the video to your own channel, feel free to do
+so. You can add the subtitles by downloading them from the talk page
+and uploading them to your video. If you let me know where you've
+uploaded it, I can switch our playlist to include your version of the
+video instead. That way, it might be easier for you to respond to
+questions on videos. (Which some people have already been adding,
+yay!)
+
+If you would like to share more resources, you can add them to the
+talk page or e-mail them to us and we can add them for you.
+
+Thanks again for speaking at EmacsConf!

+
+[[https://emacsconf.org/2021/][EmacsConf 2021]] will be a virtual conference on *November 27 and 28,
+2021 (Sat-Sun)*. If you'd like to present at the conference, please
+[[https://emacsconf.org/2021/cfp/][submit your proposal]] by *September 30, 2021*.
+
+EmacsConf 2021 is about the joy of [[https://www.gnu.org/software/emacs/][Emacs]] and Emacs Lisp. Come share
+your experiments and adventures with the Emacs text editor / operating
+system / way of life! We welcome speakers of *all backgrounds* and
+*all levels of experience*, including newcomers giving their first
+talk. What have you found exciting about Emacs lately? What do you
+wish someone had told you when you were starting out? What part of
+your workflow might inspire someone to get into Emacs or go deeper?
+
+A great way to get started with writing a proposal is to start by
+exploring the programs from previous years: [[https://emacsconf.org/2020/schedule/][2020]], [[https://emacsconf.org/2019/schedule/][2019]], [[https://emacsconf.org/2015/schedule/][2015]], [[https://emacsconf.org/2013/#program][2013]].
+You might also find some neat ideas on the [[https://emacsconf.org/2021/ideas/][ideas]] page. Feel free to
+add yours there too! If you're still not sure, come by our IRC
+channel =#emacsconf= on =irc.libera.chat= and say hi. You can join
+the chat using [[ircs://irc.libera.chat:6697/emacsconf][your favourite IRC client]], or by visiting
+[[https://chat.emacsconf.org][chat.emacsconf.org]] in your web browser.
+
+All kinds of people use Emacs for all kinds of things. We'd love it
+if EmacsConf 2021 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 expert enough to share their thoughts. If you
+let them know that you value their knowledge and maybe even suggest
+something that you think others would like to hear more about, they
+may realize that they have something worth sharing and that we would
+love to hear from them.
+
+,* Important dates
+
+For EmacsConf 2021, we are planning for 9am to 5pm Toronto/EST
+(2pm-10pm UTC) on November 27 and 28. Depending on people's
+availability, it might be two half-days.
+
+| CFP opens | August 5, 2021 |
+| CFP closes | September 30, 2021 |

+
+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 regional events (if
+you're an Emacs meetup organizer and would like to make this happen
+let's [[https://emacsconf.org/contact/][get in touch]]!).
+
+Please note that although we will try our best to stick to the above
+dates in the coming months, given the current state of the world, we
+may have to move things around a bit in case of unforeseen events.
+Thank you for your patience and understanding.
+
+,* Talk formats
+
+We'd like EmacsConf 2021 to inspire lots of different people to
+explore lots of different things in Emacs. We hope to put together a
+stream of quick ideas followed by lots of conversation over IRC and/or
+Q&A sessions, with occasional deep dives into topics that many people
+might find interesting or useful.
+
+As you think about your talk, consider what you can share in:
+
+- *Up to 10 minutes total:* What is the core idea? What do you want
+ people to do or remember? You can show just enough to get people
+ interested and then point them to where they can learn more
+ afterwards. You can answer questions over IRC, the pad, or the
+ wiki, and there's no limit to how long that conversation can go.
+
+- *Up to 20 minutes total:* How would you flesh out some of the points
+ from your 5-10 minute presentation? How can you show the pieces
+ working together?
+
+- *Up to 40 minutes total:* What would benefit from a deep dive?
+ How do you keep it engaging?
+
+When writing your proposal, please write an outline of what you plan
+to talk about if you have 5-10 minutes. If you'd like to propose a
+longer talk, outline what you might include if you had more time to
+present (up to 40 minutes, including Q&A).
+
+Here's an example for a potentially 40-minute talk:
+
+- 5-10 minutes: quick demo of the abc package working together with
+ xyz package.
+- 20 minutes: same as above, with some customization options to
+ accommodate a different workflow.
+- 40 minutes: all of the above, including modifying the behaviour of
+ the package in order to add something new.
+
+This flexibility would help us in devising the conference schedule so
+that as many people as possible could get a chance to present their
+ideas, while still allowing for featuring longer deep dive talks.
+
+Other session formats such as tutorials, workshops, and hangouts are
+welcome as well, in case you would find those other formats preferable
+to a traditional talk format. If you're interested in these or other
+session types, please let us know [[https://lists.gnu.org/mailman/listinfo/emacsconf-org][publicly]] or [[https://lists.gnu.org/mailman/listinfo/emacsconf-org-private][privately]]. We'll be
+happy to work something out with you.
+
+,* Office hours
+
+We're aware that it can be intimidating to submit a proposal to a
+conference, so we thought we'd try to help! This year, we're opening
+up the doors of our virtual offices for you to come talk to us about
+your proposals with hopes of helping you with any hurdles you may be
+facing with preparing your proposal.
+
+We'd like to publish a schedule of availabilities of volunteers for
+holding office hours. Currently these volunteers consist of some of
+the EmacsConf organizers, but we'd love to have the help of other
+members of the Emacs community as well. If you are a more experienced
+Emacs user and would like to help with this, please [[https://emacsconf.org/contact/][get in touch]]!
+
+Our first office hour this year is planned for Saturday, August 14,
+from 3pm to 4pm UTC with zaeph (Leo Vivier) at the following
+BigBlueButton room: https://bbb.emacsverse.org/b/ban-qye-fd1-5kw.
+
+,* Submitting your proposal
+
+Once you're ready to submit your proposal, the [[https://emacsconf.org/2021/submit/][submit]] page has the
+instructions on how to submit your talk.
+
+We use an anonymized submission process to reduce bias and encourage
+contribution. Identifying information will be removed from
+submissions by a conference organizer who will not participate in
+talk selection. The anonymized submissions will then be reviewed by
+a selection committee.
+
+If your talk is approved, we'd love it if you could help us make sure
+the conference runs smoothly. After we email you with the time
+allotted for your talk, we'll ask you to
+
+- prepare a prerecording of your talk, or record it with our help if
+ that'd be easier for you; and
+- schedule a short tech-check if you'd like to be able to answer
+ questions in a live session.
+
+Don't forget to subscribe to our main mailing list, [[https://lists.gnu.org/mailman/listinfo/emacsconf-discuss][emacsconf-discuss]],
+for discussion and announcements about the EmacsConf conference.
+
+We look forward to your ideas and submissions!
+
+,* Getting involved
+
+If you would like to help with the conference (planning the sessions,
+reviewing proposals, helping with infrastructure, making sessions more
+accessible, editing video transcripts, etc.), see our [[https://emacsconf.org/2021/planning/][planning]] page
+and come say hi to us at =#emacsconf= on =irc.libera.chat=.
+
+In addition to the [[https://lists.gnu.org/mailman/listinfo/emacsconf-discuss][emacsconf-discuss]] list, feel free to subscribe to
+[[https://lists.gnu.org/mailman/listinfo/emacsconf-org][emacsconf-org]] as well, for discussions related to organizing the
+conference by the EmacsConf organizers and volunteers.
+
+We'd really appreciate your help in making EmacsConf 2021 the best one
+so far!
+
+,* Commitment to freedom
+
+We remain fully committed to freedom, and we will continue
+using our infrastructure and streaming setup consisting entirely
+of [[https://www.gnu.org/philosophy/free-sw.html][free software]], much like previous EmacsConf conferences.
+An article describing our infrastructure and tools is underway,
+and will be announced on the emacsconf-discuss list when published.

+,* COMMENT How to export this file
+
+As of the time of writing this document (Org mode version 9.3.7), the
+Org links library (=ol.el=) does not yet recognize =ircs= link types,
+and will throw an error if you try to export a file containing them,
+such as 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.

+Dear fellow Emacsians,
+
+This is the second and final Call for Proposals for EmacsConf 2021,
+open until September 30. Please see below for details on how to send
+in your proposal(s), or chat about them with us in the #emacsconf IRC

+possible and I'd be happy to try and work something out with you.
+
+I'll close this portion of this email with a big thank you to all the
+folks who have submitted their talk proposal(s) or will be doing so.
+Myself and the other EmacsConf organizers look forward to reading over
+them and getting back to you about them and about the next steps. :)
+
+Best,
+amin
+
+P.S. please direct any replies to this post either to myself or to the
+emacsconf-discuss list, so as to help avoid generating extra off-topic
+chatter in the other lists cc'd in this message.
+
+P.P.S. as a volunteer-run conference, we are always looking for new
+fellow volunteers and/or organizers to help with various aspects of
+organizing and running the conference, including reviewing proposal
+submissions. If you're interested in getting involved, please come by
+our IRC channel or one of our public mailing lists (info below), or
+any of the current organizers directly and say hi. We look forward to
+hearing from you!

+Dear ${name},
+
+We would love to have your talk "${title}" as part of EmacsConf
+${conf-year}, and we've allocated ${duration} minutes for
+it. ${time-note}
+
+Your talk is tentatively scheduled for ${schedule}. The times may
+move around a bit as we update the schedule, so we'll check in with
+you if things change a lot. We've scheduled a few minutes for live
+questions and answers via web conference. Will you be available
+around this time? If there are more questions, you can also continue
+over Etherpad/IRC.
+
+Please plan to prerecord your ${duration}-minute talk(s) by ${deadline}
+at the latest. If you can, please send it in as early as possible.
+Submitting your video early lets us ask volunteers to help caption the
+video, making your talk more accessible and searchable.
+
+Please see https://emacsconf.org/${conf-year}/prepare/ for tips and
+instructions on preparing, recording, and sending in your talk. If
+you have any questions or concerns, please let us know.

+Because you sent in your video early, we were able to caption it so
+that more people can find and enjoy your talk. I've attached the
+caption text file in case you want to review it, suggest any
+corrections, or use the text in a blog post or elsewhere. Thanks again
+for your contribution!
+*** Captions pending
+Just a quick note to let you know that I've downloaded your submission for "${title}".
+
+Now we have the following files starting with ${video-slug}:
+${details}
+
+A quick check shows that it's about ${video-duration} minutes long.
+
+We'll be working on captioning it over the next few weeks. We'll e-mail
+again a little closer to the conference with schedule updates and other
+useful information. If you want to upload a new version, you can upload
+it the same way you did the previous one.
+
+Please feel free to e-mail us at emacsconf-submit@gnu.org if you need
+help updating the talk wiki page at
+${url} or if you have other questions.

+
+Could you please e-mail us to let us know if you're still working on

+can't make it this year? I know it's a strange time for everyone, so
+no worries if other priorities have come up and you don't have the

+
+If you've been having technical issues recording your presentation on

+conference with you to record the presentation. You can find a list of
+volunteers and their availability at

+If you plan to present live, please go through the self-check at

+talk is on the talk page at ${url} .

+*** E-mail text
+Dear Emacsian friends,
+
+This is it, the final stretch until EmacsConf 2021, coming up on
+November 27 and 28 less than a week from now! A few weeks ago,
+we excitedly shared the EmacsConf 201 program with you. We're now
+happy to share the conference schedule with you, i.e. the program
+plus each talk's (approximate) scheduled time slot:
+
+ https://emacsconf.org/2021/schedule
+
+All of the times listed on the schedule are in EST (UTC-5). You can
+click on each talk's title to open its page for more information,
+including its scheduled time in your local time (displaying local time
+requires running a tiny bit of AGPLv3+-licensed free/libre JavaScript
+code, included on the talk pages). For prerecorded talks, this time
+is also when the talk's video will be made available on the same page.
+Please note the '~' tildes near the times, indicating that they are
+approximations and not meant to be taken as exact times.
+
+On November 27 and 28 you will be able to watch the livestreams via
+https://live.emacsconf.org, which also has details on how to watch the
+streams using media players that support streaming (like mpv and VLC).
+Also, for Asia-Pacific folks, there will be an alternate stream by
+LibreAustralia, at 11:00-17:30 UTC+11 on Sunday, November 28. Please
+see the https://libreau.org/upcoming.html#emacsconf21 page on their
+site for more details and how to tune into the alternate stream.
+
+Last but not least, please see the https://emacsconf.org/2021 page
+of the EmacsConf wiki for more details on watching and participating
+in the conference.
+
+We hope to see you all around on November 27-28 for EmacsConf 2021!

+:SUBJECT: [need answer by Friday noon EST] EmacsConf 2021: Don't have a prerec from you yet, aaah!
+:CUSTOM_ID: follow-up-prerecs
+:END:
+
+EmacsConf is in a few days and I don't think we have your prerecorded
+video yet, so I'm getting miiiildly stressed about the schedule. And
+you're probably stressing out about it too, so let's go figure out how
+we can make this work.
+
+Option A: If you happen to have the prerecording or can get it done by
+tomorrow, we can probably squeeze it in. Please upload it to
+ftp-upload.emacsconf.org by following the instructions in
+https://emacsconf.org/2021/prepare#ftp-upload , or send us a link using
+your favourite file-sharing service (especially if FTP is giving you
+problems).
+
+Option B: If you want to present live, it might be an option. I'm a little
+worried about the potential for technical issues, since we've had
+problems with that in previous EmacsConfs. The tight schedule means
+there's not a lot of time to figure things out, and it can be hard to
+make something as focused as a prerecorded video when you're doing it
+live. We will definitely want to make sure that:
+ - your self-serve tech check works: https://test.bigbluebutton.org
+ at your convenience;
+ - we have your emergency contact information in case of frozen
+ Internet connection, etc. Please e-mail us the phone number we can
+ use to call you. We promise to use it only for EmacsConf 2021
+ emergency coordination; and
+ - you check in as early as possible (at least 1 hour before, so we
+ know if the speaker before you needs to extend) and let us know
+ that you want to do it live https://emacsconf.org/2021/speakers .
+ We keep adapting the schedule as things come up, so please check
+ https://emacsconf.org/2021/schedule/ on the day of the conference.

+If there are technical issues or your talk runs a little over time, we
+might have to stop streaming it on the main stream when it's time for
+the next talk. We may be able to continue streaming it on the
+alternate stream. If so, people can continue watching it there if they
+wish to.
+
+Option C: If you can't make it, that's okay. Life gets crazy
+sometimes. Please let us know and we can update the wiki. If you
+happen to be able to make a prerecorded video afterwards, we can add
+that to the wiki, playlists, and announcements. We hope you can join
+us next year.
+
+Since EmacsConf is *this weekend* (aaaaaaah), please let us know by
+tomorrow noon EST (Friday; 9AM PST, 5PM GMT, 6PM CET) so that we can
+keep the time allocated for you in the schedule. If we don't hear from
+you, we'll probably reallocate the ${duration} minutes reserved for you so
+that other talks can have longer Q&A. If you can still make it, check
+in early and let us know so that we can try to work out an alternate
+stream for you. Hope to hear from you soon!

+Thank you so much for sending in your prerecording. We were able to
+caption most of the talks, yay! That will help more people appreciate
+the talks, and it'll make it easier for people to look up technical
+terms too. The talks will be streamed with open captions, and the talk
+pages will have the videos with closed captions when they're streamed.
+
+We're still adapting the schedule as stuff comes up, so please check
+the schedule again on the day of the conference and check in as early
+as you can. (Check-in instructions: https://emacsconf.org/2021/speakers)
+
+--- Presenting live? ---
+
+If you really, really, really want to present live, we can keep the
+prerecorded talk as a backup plan. I'm a little worried about the
+potential for technical issues, since we've had problems with that in
+previous EmacsConfs. The tight schedule means there's not a lot of
+time to figure things out, and it can be hard to make something as
+focused as a prerecorded video when you're doing it live. If you want
+to present live, we will definitely want to make sure that:
+ - your self-serve tech check works: https://test.bigbluebutton.org
+ at your convenience;
+ - we have your emergency contact information in case of frozen
+ Internet connection, etc. Please e-mail us the phone number we can
+ use to call you. We promise to use it only for EmacsConf 2021
+ emergency coordination; and
+ - you check in as early as possible (at least 30 minutes before) and
+ let us know that you want to do it live
+ https://emacsconf.org/2021/speakers
+Going with the prerecorded video is probably the least-stress option
+for everyone, but we wanted to offer you the option to go live just in case.
+
+Looking forward to seeing you soon!
