Requested features... sure, go ahead, but bear in mind we may not be able to implement for a while.
Using Firefox 2, I have similar issues. The .com domain appears to be working fine, but I'm having problems with the .org domain. The same problem is also present in IE6. In IE with a screen resolution of 1024x768, the sidebar also gets pushed down below the posts and comments.
