Just an observation: when I click on a sidebar item (stock firefox 3.0.4 from Fedora 10) I get a bunch of stuff overlapped (ie, text on top of text), making it unreadable. Oversights like this would be a be reason to lose all confidence in whatever the site is supposed to represent.
The overlap is probably vertical from the /div positioning. If you got some "Intro to html and javascript", you could do this yourself in a couple of days. And do check it on more than one browser!
