-Hi, ${speakers-short}!
-
-${prerec-note}Here are the instructions for uploading the video${plural} for your talk${plural}.
-You can find the latest version of the instructions at https://emacsconf.org/2022/upload/ .
-There are two ways to upload your talk${plural} this year, so you can pick the one that works best for you:${wrap}
-
--   Web-based: <https://ftp-upload.emacsconf.org> , password emacsconf
--   FTP: host: ftp-upload.emacsconf.org, port: 21, username: anonymous
-    folder: upload-here
-
-If you upload slides and other resources, we can include them on the
-talk page when your talk goes live. If you happen to have a script or
-a transcript, please include them as well (it’ll speed up the
-captioning for us).
-
-Please start your filenames with the ID for the talk that it&rsquo;s for:
-${slugs}.
-
-If you&rsquo;re still working on your talk, you might find the tips at
-<https://emacsconf.org/2022/prepare> useful. In brief:
-
--   at least 1280x720 resolution
--   we recommend dark text on a light background, with enough contrast
-    to make it easy to read
--   if possible, use a headset or external microphone to record audio
--   leave 5 seconds of quiet at the end of the video to facilitate noise
-    reduction for us
-
-Please plan to upload your talk by November 4 (next Friday) so that we
-can get started preparing it for streaming. If you can&rsquo;t make it by
-then, we can accept later submissions, although it&rsquo;s a bit more of a
-scramble and our stress levels go up as the conference approaches. =)
-We&rsquo;d really appreciate the extra time for captioning and
-double-checking. Thank you for your help in getting ready for a smooth
-EmacsConf 2022!

+
+Hi, ${speakers-short}!
+
+Just a quick note to let you know that I&rsquo;ve downloaded your
+submission for &ldquo;${title}&rdquo;. We&rsquo;ve added your submission to the backstage
+area at ${backstage} (username: ${backstage-user}, password:
+${backstage-password}), and we&rsquo;ll post the files on your talk page
+when the talk is public. A quick check shows that your video is about
+${minutes} minutes long (${time} minutes budgeted).${wrap}
+
+We&rsquo;ll be working on captioning it over the next few weeks. We&rsquo;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 ${url} or if you have other
+questions.${wrap}
+
+Thank you so much for all the work you put into preparing a talk for
+EmacsConf ${year}, and thank you for submitting the prerecorded video
+before the conference!
+

+
+Hi, ${speakers-short}!
+
+${prerec-note}Here are the instructions for uploading the video${plural} for your talk${plural}.
+You can find the latest version of the instructions at https://emacsconf.org/2022/upload/ .
+There are two ways to upload your talk${plural} this year, so you can pick the one that works best for you:${wrap}
+
+-   Web-based: <https://ftp-upload.emacsconf.org> , password emacsconf
+-   FTP: host: ftp-upload.emacsconf.org, port: 21, username: anonymous
+    folder: upload-here
+
+If you upload slides and other resources, we can include them on the
+talk page when your talk goes live. If you happen to have a script or
+a transcript, please include them as well (it’ll speed up the
+captioning for us).
+
+Please start your filenames with the ID for the talk that it&rsquo;s for:
+${slugs}.
+
+If you&rsquo;re still working on your talk, you might find the tips at
+<https://emacsconf.org/2022/prepare> useful. In brief:
+
+-   at least 1280x720 resolution
+-   we recommend dark text on a light background, with enough contrast
+    to make it easy to read
+-   if possible, use a headset or external microphone to record audio
+-   leave 5 seconds of quiet at the end of the video to facilitate noise
+    reduction for us
+
+Please plan to upload your talk by November 4 (next Friday) so that we
+can get started preparing it for streaming. If you can&rsquo;t make it by
+then, we can accept later submissions, although it&rsquo;s a bit more of a
+scramble and our stress levels go up as the conference approaches. =)
+We&rsquo;d really appreciate the extra time for captioning and
+double-checking. Thank you for your help in getting ready for a smooth
+EmacsConf 2022!

-Hi, ${speakers-short}!
-
-${prerec-note}Here are the instructions for uploading the video${plural} for your talk${plural}.
-You can find the latest version of the instructions at https://emacsconf.org/2022/upload/ .
-There are two ways to upload your talk${plural} this year, so you can pick the one that works best for you:${wrap}
-
-- Web-based: https://ftp-upload.emacsconf.org , password emacsconf
-- FTP: host: ftp-upload.emacsconf.org, port: 21, username: anonymous
-  folder: upload-here
-
-If you upload slides and other resources, we can include them on the
-talk page when your talk goes live. If you happen to have a script or
-a transcript, please include them as well (it’ll speed up the
-captioning for us).
-
-Please start your filenames with the ID for the talk that it's for:
-${slugs}.
-
-If you're still working on your talk, you might find the tips at
-https://emacsconf.org/2022/prepare useful. In brief:
-
-- at least 1280x720 resolution
-- we recommend dark text on a light background, with enough contrast
-  to make it easy to read
-- if possible, use a headset or external microphone to record audio
-- leave 5 seconds of quiet at the end of the video to facilitate noise
-  reduction for us
-
-Please plan to upload your talk by November 4 (next Friday) so that we
-can get started preparing it for streaming. If you can't make it by
-then, we can accept later submissions, although it's a bit more of a
-scramble and our stress levels go up as the conference approaches. =)
-We'd really appreciate the extra time for captioning and
-double-checking. Thank you for your help in getting ready for a smooth
-EmacsConf 2022!

-- Issue: zaeph was dropping frames and couldn’t pay attention to as many things as he wanted
-- Issue: corwin needs assistance to not be locked in his chair for the whole conf.  Premptively, zaeph can do it by broadcasting OBS scenes via the rtmp (instead of just his webcam).
-- With a long day, we may want to be able to schedule hosts/streamers/publishers in shifts
-- Ideal: Easy reproducible setup to spin up an OBS VM with scenes set up, allowing multiple users to connect to it at the same time. Maybe x2go or vnc? VMs with 8 vCPUs and a vGPU cost more, so it would be good to figure out what's needed, spin it down, and then spin it up maybe the day before or something like that.
-- Plus points if we can control the OBS via password-protected websocket so we can tell it to switch scenes (and even more points if we do so from Emacs, maybe via that obs-websocket.el ;) ). MPV is also controllable via IPC, so we can use the same MPV player and then switch videos around. Maybe mpvc? https://unix.stackexchange.com/questions/664728/how-can-i-control-mpv-in-command-line
-- Probably Linode's Dedicated 32 GB + RTX6000 GPU x1 at $1.50 an hour for 2-3 days + dev time, since live.emacsconf.org is in Linode as well
-- We should also look into normalization across the board, especially if we have BBB participants.  pipewire + easyeffects on the box might be the easiest way to do it.

+- bandali doesn't have much cognitive bandwidth at the moment, so we can keep things simple with OBS on laptops

+- Issue: zaeph was dropping frames and couldn’t pay attention to as many things as he wanted
+- Issue: corwin needs assistance to not be locked in his chair for the whole conf.  Premptively, zaeph can do it by broadcasting OBS scenes via the rtmp (instead of just his webcam).
+- With a long day, we may want to be able to schedule hosts/streamers/publishers in shifts
+- Ideal: Easy reproducible setup to spin up an OBS VM with scenes set up, allowing multiple users to connect to it at the same time. Maybe x2go or vnc? VMs with 8 vCPUs and a vGPU cost more, so it would be good to figure out what's needed, spin it down, and then spin it up maybe the day before or something like that.
+- Plus points if we can control the OBS via password-protected websocket so we can tell it to switch scenes (and even more points if we do so from Emacs, maybe via that obs-websocket.el ;) ). MPV is also controllable via IPC, so we can use the same MPV player and then switch videos around. Maybe mpvc? https://unix.stackexchange.com/questions/664728/how-can-i-control-mpv-in-command-line
+- Probably Linode's Dedicated 32 GB + RTX6000 GPU x1 at $1.50 an hour for 2-3 days + dev time, since live.emacsconf.org is in Linode as well

+Please feel free to e-mail us at emacsconf-submit@gnu.org if you need

+Thank you so much for all the work you put into preparing a talk for

+Hi, ${speakers-short}!
+
+${prerec-note}Here are the instructions for uploading the video${plural} for your talk${plural}.
+You can find the latest version of the instructions at https://emacsconf.org/2022/upload/ .
+There are two ways to upload your talk${plural} this year, so you can pick the one that works best for you:${wrap}
+
+- Web-based: https://ftp-upload.emacsconf.org , password emacsconf
+- FTP: host: ftp-upload.emacsconf.org, port: 21, username: anonymous
+  folder: upload-here
+
+If you upload slides and other resources, we can include them on the
+talk page when your talk goes live. If you happen to have a script or
+a transcript, please include them as well (it’ll speed up the
+captioning for us).
+
+Please start your filenames with the ID for the talk that it's for:
+${slugs}.
+
+If you're still working on your talk, you might find the tips at
+https://emacsconf.org/2022/prepare useful. In brief:
+
+- at least 1280x720 resolution
+- we recommend dark text on a light background, with enough contrast
+  to make it easy to read
+- if possible, use a headset or external microphone to record audio
+- leave 5 seconds of quiet at the end of the video to facilitate noise
+  reduction for us
+
+Please plan to upload your talk by November 4 (next Friday) so that we
+can get started preparing it for streaming. If you can't make it by
+then, we can accept later submissions, although it's a bit more of a
+scramble and our stress levels go up as the conference approaches. =)
+We'd really appreciate the extra time for captioning and
+double-checking. Thank you for your help in getting ready for a smooth
+EmacsConf 2022!
