Would be helpful to have a screenshot or something so I can see what's up before approving camera/mic access!
I feel like there shouldn't be a #public room. It is basically Chatroulette.
You can turn your camera off once you're in a room too - I actually made this to try and host my birthday party next month where it would be nice to see everyone :)
I really like the idea of being able to mingle, and "walk" around to chat with different groups, all at the same party.
