Thanks Gustaf,
I wasn't aware until you pointed it out. I was looking for sql create statements in xotcl and xowiki in the sql folders but I did not look closer inside the xotcl chat-procs.
Sure enough, you record the chats in a table chat_msgs.
While in the subject of management pages. What do you envision these management pages should look like.
I was going to create a simple page for admins to view the rooms in a list, clicking on the room id opens up the chat messages for that room.
