Great, very good site.
Just some improvements, you may wish to concider.
1. On top advert, i recomend makeing the ad BG, same color as the space provided, or other way arround

2. Your left menu, some items have background colors, some dont? .. Maybe removeing the BG colors to make it fit in design?
3. The TOP LINKS, lol. Needs a button image, like rest of content.
4. Maybe too many ads, on the opening of the page, 4 in the screen, scroll down. and theirs none?
5. Make the cateagorys, the same height.
Just some minor things that i whould do. One of the best implementations of the script, i have seen for a long time.
Please ensure you give true opinions on the launch of my new FunShed, site. Ill post it up in about a week.
