I'm working on a new skin at the moment for my forum (works on 1.2.3). I'm having problems locating which part controls the width of the sidebar of posts. Firebug didn't help this time either. I've got the avatar holder etc all set to the right width, but the sidebar itself that stands behind it won't widen to the same specs.
In the example above, the lighter brown on the right is the main content, and you can see the border of the avatar holder. The sidebar itself hasn't been given a background so you can make it out - where in either the style properties or templates do I go to edit the width?
