One thing they use on Gamefaqs to good affect is the split board concept.
They tend to have two (or more forums) for popular games that tend to draw a lot of posters (and thus a lot of posts)
How about giving us a KotOR2:TSL Social board to go with the Game Discussion board?
KotOR chitchat isn't really game discussion, but on the other hand it's definately not off topic.
As board volume increase, this will make it easy to sort and find threads of intrest, be they pure game discussion or kotor chitchat.
