Re: How do I clear the menu bar?
/mu-plugins/bp-core/bp-core-adminbar.php but the css gets enqueued in bp-core-cssjs.php in the same dir.
There’s a bug in RC-1 that sends out the admin bar css after the site-wide.css so including your mods in there won’t do much good. Patch in : https://trac.buddypress.org/ticket/555
The wp_footer action ‘calls’ the admin bar.
