I understand that GroupChat is being deprecated, and that MultiUserChat should be used instead, going forward.
But, how would I know whether or not a room supports MultiUserChat?
I’‘ve noticed that after joining a room, I’'ll get a message that says “This Room Supports the MUC Protocol”, but is there a way to tell ahead of time?
Also, if a room doesn’'t support MUC but I try to join using MultiUserChat, what kind of error will I get?
Finally, if a non-MUC room needs a password to join, how can I do that with the GroupChat object? Or is it that only MUC supports the concept of having a password to join?
