Looks great, the backdrop simulating the octagon is very clever, the logo to the left doesn't look bad either. What's missing is a visually attractive header/banner. The text banner alone simply doesn't get it. I'd much prefer to see some visual action there, something that represents the UFC and all other MMAs, while you're still including the name of the forum.
NP has skilled designers/graphic artists that can produce something good for an acceptable price.
A favicon would also be nice, especially if you could animate it to the effect that the letters "FCF" are rotating through.
Other than that, you kept the categories low, the looks crisp - works for me - Great Job!
