Active chat rooms not in ofMucRoom table?

Hi,

I have a script that dumps Jabber conversations daily and I’m trying to do the same for chat rooms. I can get the bodies of messages from ofMucConversationLog, but I noticed that not all of the entries for roomID had a corresponding entry in ofMucRoom.

Further in my admin gui I see rooms that are current and active and set to allow logging that have no row in ofMucRoom.

Should I expect those things? If not, what is ofMucRoom for?

thanks

Kevin
