Ok, so some things have changed apparently. I am trying to adjust the forum width, so that the entire window is used, instead of it being center and leaving a ton of space on either side. It is an aftermarket theme, that i built off of someone else's work. That person is not available, and the issue is that there is no longer a style.css in 2.0RC5.
Now, in the core theme's index.css I can find the proper place to change the forum width. This does not appear to exist, however, in my theme's index.css. And i tried altering the core, which does nothing (obviously) for my theme.
Attached is a copy of my theme's index.css. I have never been too keen with css, so i'm not sure how to add it in (if i can), or if another way exists. I tried changing the divwrapper, which just shot the content of the forum way out past the body of it.
Any insight is greatly appreciated.
