The breadcrumbs above the content of the page look like they are about 50px too far left. The "Home" sits on top of the graphic, and it makes it hard to read.
Should be: style.css:496
Edit: Unrelated, but didn't want to spam up the repairs forum, especially on my first day of not just lurking. I think an edit to the .forum-post css in advanced_forum.css on line 73 would be nice.
Current:
advanced_forum.css:73
Proposed:
advanced_forum.css:73
.forum-post{} //obviously this doesn't need to stay, but I'm suggesting remove the border.
advanced_forum-structure.css:178
It fixes the ugly "Printer-Friendly Version" link after the first post in a thread, as well as a lot of the overlapping of the borders and whatnot.
Minor fixes, of course.
