I would really like to submit runs without a youtube but rather a video from a different area you can post them on, since youtube is completely broken for me, everytime I go there nothing works and sometimes it just crashes my browser. Is twitch an option?

yes twitch works but you should ask the mods if theyll be okay with whatever you end up using though id say everyone is fine with twitch

Make sure if you’re submitting streams that you highlight them so they aren’t deleted.

@XNunaAZ generally anything is allowed if someone can watch it without having to sign up for something. Some people have used vimeo, a ton use twitch, and some even submit stuff through things like google drive for whatever reason. Either way, what browser are you using? 99999% of browsers are compatible with youtube, haven't heard of it having these issues before.

Twitch also supports uploads of offline recordings (essentially, YouTube's original function).
