well just installed it into my test forum, very easily by the way

what I meant with usergroups, is that we can set certain restrictions in usergroups so they cannot see forums etc, what i am after is that one set of users will see only one room, and the next, like admins will see all the rooms, and that they will only be able access these rooms through my website only, no external chat will be able to connect to it.
One thing though, is how do I create rooms, I am connecting to your test environment right now?
