This isn't really a bug, but more like a small thing that drives me insane for no apparent reason:
Across your website, you have about 4 different themes. If you could make the website use one theme, then I would be less twitchy when I use your website. <img src="smileys/smiley29.gif" border="0" align="middle" />
P.S. I prefer the theme the forums use the best.
