BuddyBar Widget by slushman was originally developed for the Towermix Network at Belmont University‘s Curb College of Entertainment and Music Business. They didn’t want the BuddyBar from the default installation of BuddyPress, but still needed the links for editing profiles, etc. The BuddyBar Widget places all the links on BuddyPress’s BuddyBar in a sidebar widget.
When a user is not logged in, the widget shows a login form (with a link to the registration page at the bottom)
When a user is logged in, it shows all the links a user would need to manage their account
Multiple Instances are possible.
