heya PT!!
excellent design. there are a few parts i dont like or disagree with, but... i love the fact that you at least attempted to majorly customize the UBB, and make it work for you.
the one thing i'd nit pick the most tho would be the graphic image BG, behind the posts. i dont mind that its there (cool effect!) but you should dim it or blur it or ghost it so that the text is easier to read (some people i saw used green text, which is impossible to read over the bg image).
regardless, great job on it!!!
