I've been working on my wordpress in firefox, finally getting it how I want it to look. Then I try it in IE, and it's a horror show.
If you're using IE, you can take a look over here: http://www.wetacollectors.com/
If you're not using it, I will describe it to you- everything looks fine except the sidebar has slid waaaay down to near the bottom of the page. It doesn't begin until the last post entry has been shown.
