I think that these are good: - recording IPs - # of views - lockable threads - making stickies - # of replys - last person to reply - subscribe to thread - reply with quote
I forgot about subscriptions. Does it make more sense to subscribe to the entire thread or to only sections of a message? In the latter case, someone might post a message in the wrong place (they always do) that might be of interest to you and you wouldn't get any notification. Of course, if a subscription is to the whole message, you'll get notified of all replies, which could be both bad and good.
