I would like to have a list of rooms but I would like to be able to make some of them inactive.  Also, I only want chats to be going on when there is a superviser.  Can I do this?  What I want to do is still keep the rooms so that I don't have to keep re-creating them but not allow visitors to log in when there is no supervision.  The settings or "flags" in the Manage area don't seem to make any difference.
