Alrighty, I've now stealthily sneaked into the tea room!
Don't know yet what's going on there, gonna translate the buttons now, hope this will clear things up a bit. Guess one of the buttons is joining a room?table? that I can highlight, and the other button is for creating a new one?
Will keep an eye on it, although the time zone might become an issue, since I'm on CEST (I'm a night owl, however)
