The "Lightning Talks" seem to be scheduled 10:45 - 11:30am UTC (the first two days of conference), and not 17:30 - 18:50 UTC
Do I understand correctly?
I think all times are local time in Berkeley, as the day started at 8am their time last year.
They are on PDT - so use an online time zone convertor to find out what times are what in your own time zone 
That's super helpful. Thank you, Simon!
An actual useful schedule with times in all our users' common time zones is at https://tinyurl.com/snapcon2021.
Oh, thank you. I really like spreadsheets more than data shown on website.
Hi, I have two validated proposals.
Can you tell me how, concretely, this will play out: is it going to be a zoom session ?
Right now, I am preparing my keynotes in 16:9 display format, do you think it will fit?
Yes, Zoom. My guess is that Zoom will letterbox your slides but it'll work. See you soon!
If anyone plans to play a video and sound, for example included in a slide, it seems that both "sharing computer sound" and "optimization option" need to be enabled first as shown here at 4min 17sec into the tutorial.
When I try to join a session (with a link to https://www.snapcon.org/conferences/2021/program/proposals/284/join) it says You are not authorized to access this page. in yellow and redirects me to Snap!Con 2021. How do I join?
We are all having same problem
Ok. Hopefully someone fixes it before it starts.
This is now fixed, right?
Yes.
