Hi vimarc,
I really like the style - it's clean, simple, and well-contrasted. Your forum icons look really nice as well! Could you modify the toplinks/login background to match the color scheme in the navbar? I think a lighter blue would look good there, instead of the default vB4 turquoise color. Your spam-o-matic statistics are a bit hard to read in light grey, but other than that I couldn't find any issues! Loads nice & fast as well

Good job!
