I stumbled across some errors in Firefox. Not sure if they apply to IE and other browsers, and they don't affect my ability to use the forums. They might just be cosmetic stuff, by Firefox has them listed in it's Error Console. I only saw them because they displayed when it came up for another site.

Anyways, when I hit the main page:
