User blog:Sprinklemist/Chat Rules?

I added the chat function to the wiki, but some users were requesting some courtesy type rules. What should they be in general? Does anyone know if there's a way to set them on the chat, or would it simply have to be a page, perhaps?

Some obvious rules would be no profanity, sexual comments, or bullying. If people witness it report it to an admin.

In general, if the chat is overly abused (with the above or badmouthing other users), it can easily be taken off.
