I like the look of the site, you blend the Google ads in well. I would increase the size of the navigation bar, and might try improving the top image of the site - make it a bit more relevant to the site. Good luck with it, its looking great already so far.
nice site for start. maybe you can make the logo a little small. so the visiters wont see the scroolbars.
really a nice website and topic is too interesting, with your site i decide to use that script other then phpbb, theme you use is a bit light then blue it should be a bit darker
