+Nothing is urgent, blocking it, or being blocked by
+it, so you can play around with ideas.
+
+We're experimenting with two tracks this year, so we expect that some
+people will join midway through a talk or Q&A session and
+would like to reorient themselves. Some Q&A sessions may end
+early, so we would like to reassure people that they're in
+the right spot for the next talk. Most Q&As will be done
+live, but some Q&As will be done over IRC, so we need to
+point people to the right place.
+
+and if there's room for a little extra info like public e-mail
+addresses or pronouns, that can help people when they discuss
+things. That info will be in the pad and IRC, though, so it's
+also okay to omit it
+         
+
+
+We can programmatically replace strings in
+SVG from Emacs, so we can easily use that as an overlay.

+Hello, everyone! Here's the weekly update on what's happening backstage
+for EmacsConf 2022 in case you notice something that you want to help
+out with. =)
+
+- Help wanted - Captioning: There are three talks open for captioning
+  in <https://media.emacsconf.org/2022/backstage/> , so feel free to
+  e-mail me if you'd like to reserve one. I've tweaked the captioning
+  process a little bit so that I can reflow the transcripts into
+  shorter subtitles before people edit the captions, so editing is
+  easier to do because you don't have to split along the way. (If
+  you're curious about the technical stuff, I switched to manually
+  splitting the text using emacsconf-reflow from emacsconf-el and then
+  the using aeneas for forced alignment, because I couldn't figure out
+  how to get torchaudio unstuck sometimes.)
+
+  If you don't have the username and password for the backstage area
+  and you would like to access it, please e-mail me and I'll send you
+  the details.
+
+- Help wanted - tech checks: For sessions with live Q&A, we'd like to
+  set up tech-checks with speakers to make sure that their setup works
+  well with BigBlueButton. A rough outline of the process is in the
+  tech-checking protocol heading at
+  <https://emacsconf.org/2022/organizers-notebook/#tech-checks> . If you
+  would like to help with tech-checks, please e-mail us with your
+  general availability (including timezones) and preferred public
+  contact information so that we can include you on the list at
+  <https://emacsconf.org/2022/prepare/#tech-check> and in the e-mail to
+  speakers.
+
+- Help wanted - intro/intermission slides, OBS overlay, ??: It might
+  be interesting to design something to show right before and right
+  after a talk so that people can see the title, speaker name, talk
+  page URL, Q&A info, pad URL, pronouns, etc. Ideally we'd be able to
+  generate a whole bunch of these from the talk data, so maybe SVG or
+  a TikZ picture? If this is your jam, let us know.
+  
+- OBS in the cloud: We've been able to figure out how to stream both
+  streams using OBS, VNC, and PulseAudio on Ry P.'s virtual server, so
+  it's even more likely that we're going to pull off two tracks this
+  year. Yay!
+
+- Tom Purl has joined as a captioning volunteer. Hi Tom!
+
+This week we hope to get lots of talks submitted, processed, and on
+the way to being captioned. We're also planning to make the captioning
+workflow even better, and to improve the OBS streaming workflow. Whee!
