And you know that 'but' means ignore everything that came before. =)
Actually that's not true, you've obviously done a good bit of work and it looks great. I love the cheese theme and the way you've got the topic icons in the 'holes' in the cheese. =)
My only nitpick is that you site wastes more than a third of my visible browser window with the Artificial Cheese Graphic. Which means I have to scroll over to see the login and poll options. I personally loath horizontal scrolling and sites that want to force me to maximize my browser window. Especially when I could see all the information on the page if there wasn't a huge graphic taking up space, or a table with a forced (and 99% of the time completely unnecessary) table width.
Good work though.
