Forgot to ask somethings more.
want to know about the number of contemporary user access. How may people can access contemporarily to muc.
And I found that when logging in as an administrator, and try to create a room in group chat menu, it does not allow a domain name put after the name of the room in the field. for example, I try like this 3 kinds 3 times: name : meeting or meeting.domain.com or just default name.
All in case was fault. So, is it possible if I give another domain to muc, and setup mu-conference provided by jabberd2 and make them linked?
And last, when I turn off or close a browser without logging out, I see im still logging in on another machine.
