Use table instead of div for content. If you set fixed width for div, it won't expand when content is larger than its width, but tables do expand. It usually shouldn't be done as tables shouldn't be used for layout, but it works much better for situations like one you have on your forum.
Funny you say that tables shouldnt be used for layouts when you use them apparently on your layouts? :P Anyways, thanks...Ill check that out and say if it does what I need it to do. ^_^
