I would still LOVE to see a reply-by-email added to UBBThreads. If I could respond to a forum message without leaving my email client, that'd be great.
Within the expanded, threaded view, it'd be cool if you box each thread, so that it was definitive as to where one thread ended, and another began.
Add a field to user table that states "last accessed" (anything from reading a forum to posting a message; any activity). This way I could see when a person last visited the forum. You could then eliminate the "Who's Online" table, and just select against this column asking for those who have visited within the last 10 minutes.
