Another suggestion

You should have a set of rules for every different Forum. The rules will most likely
vary from forum to forum. If you're in general discussion, then the rules may be not
to post pokemon topics in it and that you should post them in Pokemon General(if
there is not already, there needs to be a pokemon general), so the General is not
flooded so many different topics. It makes it kind of easier to focus on a main topic
in the individual forums.
