I just hope some of the colours are made more appropriate. Less saturation and more complimentary colours plx.
Also the build professor type is horrible in small font. Plus, if you're gonna use the (novel) tf2 type face then you might as well make novel buttons to go with it. Whacky type in a clean cut button looks weird. The forum should be clean or it should be novel, not both.
edit: Also, do we always see our own signature? I noticed mine is visible but others arn't; it also seems odd to hide peoples sigs, a lot of people use the links in mine and it'd be annoying if people missed them...
