No prob, it looked good and except for a couple things was fine. I can't do css yet, so ya got me beat. You can go wider in the future if you want as well, 750 width will be good for even 800/600 and may give you more room for ads and whatnot.
You had 2 sponsors per page which is good, i noticed the link at the bottom to your homepage so it would count as the 3rd link usually. If you wanted to get traffic to it, you could make it a little more prominant being that it counts as one of your outlinks anyway.
Good luck
