in ie6, the right column is under the left column (1), not next to it, and the wii logo in front of every category is a few pixels off (2) (as someone else already said) and there are huge spaces between those categories (3). And the rollovers don't work, it just underlines the text (4). now, even more the numbers that show the number of threads and posts in a category, aren't vertically centered (5) (which is probably the cause of the gap between the categories)...

heres an image where you can see what I mean
