BuddyPress.org

Well, in short, I needed to make a /css folder in my theme folder, copy the new bbPress css file from wp-content/plugins/bbpress/templates/default/css/bbpress.css and rip out all the mobile related entries that where all in the bottom end of that file.

Problem solved though it isn’t a very elegant solution and I’m sure this cause havoc for lots of other themes that aren’t responsive.
