Quick update: encountered a problem. In rumorville, the forum title is so dang long that it pushes the secondary navigation bar ("Husker Watchsites, 2009 Schedule, etc") down a line and messes up the centering of the advertisement pretty badly (

Amendment to the style definition:
Code:
<div style="text-align: center; padding-top: 5px; clear: both;">
I'm not sure the PADDING-TOP is even necessary with CLEAR in there. CLEAR stops floating elements (such as the secondary nav bar) from being on either side of the advertisement, which I suspect is what was causing the centering issue in the first place. Not that the extra 5px of space will cause huge problems, but I think it's unnecessary now.
