I'm not a webdesigner so I do not pretend to be an expert, but I think I did a great job with one of my sites. I have this site for 6 years, this time I did a major redisign, I still had frames !!! please visit: http://www.tuning.online.pt I modified the forum skin to match the same design: http://www.tuning.online.pt/forum/ I still isn't 100%, i'm still working on it...
Whoa, that really is a great layout xD The ads blend in really well (maybe too well, xP) and don't stick out making the page look ugly. So its all good xD
Interesting website you have , nice design . Try to look more careful to the header part and come up with some ideas. Good luck !
