Sorry for the late reply. At home and at school I have IE 6 on Windows. The upper-most most recent post is hidden.
Also, could you bring back some of the features on the bottom of the page? Who's online, the "more stats" page with most-viewed, most-replied, top posters, that sort of thing?
I attached screen captures of how the top and bottom of the pages look. It's cut off on the right-hand margin only in the paint program, not on my browser.
