Like the portal, the skin design is fairly clean and nice on the eyes for an off the shelf. I am not such a fan of the black against the grey though. It looks too much like your elements are 'floating'.
I have to agree with hitman... far too many forums. I seldom ever see busy sites with that many forums - reason being that its far too easy to overlook a forum while browsing around. I would crunch them all down to about 5 and then expand as your traffic grows.
Just my 2 cents
Keep on it!
