Okay seriously...
Censorbot - a bot that detects censored words, and makes a post warning the poster after the offending post.
Congratulatorybot - a bot that makes a posts after the post of a member when the member has made 1000 posts (or something like that).
Flamingbot - a bot that detects flaming (by looking at certain keywords like "you idiot" or "you are stupid" and makes a post in that thread to ask people to calm down.
That's it for now...
