Wider Body

I can't figure out how to widen the main body of our main blog.

I can make it wider, but then the buffer gets screwed up, and it's touching the sidebar (which looks stupid). So if anyone knows HTML, it would be cool to get the main bar a little wider, so it can contain GameTrailers videos...

Let me know if you have trouble accessing the source code. You should be able to access it under Template, then hit "Edit HTML"
