Heyo! great question.
1) Tricky to answer. Depending on the amount of submissions, I want to make this either a 1 or 2 day streaming event. If I get more than 20, the streaming will be broken up into two days on the 12th and 13th (Monday and Tuesday), each starting at 8PM ET. If I get less than 20 submissions, I will be streaming only on the 13th (Tuesday), again, starting at 8PM ET. I recommend you keep an eye on my Twitter for more information as it develops, and you can of course watch the Discord and my Twitch itself!
2) The stream will be archived and kept forever! If you can't make it, don't worry, you'll have future chances to watch it. The stream will be viewable in my Twitch Videos section. The stream should be visible there nearly immediately after it's completed.
Looking forward to trying everything out! :D
