it just seems to crowded. doesnt all really flow. too much text and stuff everywhere. also not really liking the design much either, just seems too gray and bubbly. reminds me of some default phpbb theme.
I agree everything is too close together as well as there appears to be a lot of unnecessary boxes around everything especially towards the bottom of the page. You could also try using some different colours as backgrounds as the white background makes the page look kind of plain.
