hey,
the site in question is at
http://katieherman.com/acelin/
the problem lies in IE's rendering of the site. I validated it. all that's left is trivial stuff like missing image alt tags. Basically, the entire header/navigation/top is all messed up. What it looks like in firefox is what it's supposed to look like.
Feel free to take a look, as I have a feeling (judging by the problem) that the error is just due to a tiny bit of whitespace that I'm code-blind to becuase I've been working on this site for so long and that you guys will be able to pick out in an instant.
Thanks in advance and take care,
Cameron
