Briefly, if you use Internet Explorer to visit this site, there seems to be some problems with the main index page displaying properly, particularly the left sidebar. Our crack staff is hard at work trying to figure out how to convince all of you to start using a more modern browser like Safari or Firefox attempting to fix this issue.
update, thanks to kind help from Bruce21, this might be fixed. I did have an extra div tag after all! Doh!
Looks like you have a JavaScript error around line 7000. Embedded in the JavaScript you have included which is not JavaScript.
