Need coding help... one last page to fix

[Chimpie]

Mine is two, using the same font size as it was before. I'm also not on a widescreen, which is important that it's not. The set up also requires a horizontal scroll bar, something not needed before.

EDIT: Going between the home page (www.skywarnforum.org) and the forum page you will see that the box on the left is wider on the home page (and every other page) (which is the correct size) than the forum page.

Any chance we can fix that?
