yea, the width of the forum as a whole. if you click "choose style" at the top where the wii unite banner is, the other options are all the same layout, but it still makes the site a lot easier to look at lol.
I see. Unfortunately the only way I could do that is by changing the stylesheet for default2 (the... default one), and I'm not sure I have the ability to do that. I'll look into it, although it seems most of the other themes don't have proper formats (words are out of their boxes at the top, for example).
