I doubt more forums will be needed, considering most people don't use the realm forums, and not everyone who uses the realm forum will come here, and it's already split into 4. The only thing I could think of adding is an "RP Critique" thread, for OOC comments on RP stories as Aitana suggested on the realm forum. (Think it was Aitana could be mistaken.)
That would help keep OOC comments from derailing an RP thread. But other than that I think we're good.
@Sneigh, there is something you can fill in on your forum profile to have some text under your name. It's not automtatic, but you could put your guild name where mine says "Viceroy of the Kingship."
