Forum Forum Posts Only Using Up Half the Available Space

[محروم.كوم]

I've modified my vB to a different width from the retail version and it now the page layout works to my liking. The problem though is that all of my forum posts are only using up half of the space that's available to it.

Example:
A forum post that is
on my site would
appear like this and

not use all of the
available space.

Another thing too: if I attempt to edit a post, the form is all crammed into that same space. If I create a new thread, the form takes up the width I defined, but the finalized post still suffers the problem of being crammed in by an invisible barrier. Where do I go to have the post width as "100%"? __DEFINE_LIKE_SHARE__
