Such a great plugin. I use it all the time for multisite and BP. Only thing is I can never use biography option since it only pulls wp author info. All my author infos are set in the xprofiles of bp and they don't have access to edit their wp-admin/profile.php page, in my case.
Will you consider adding support for selecting a xprofile field eg. "About" (or really any field, I input) that will show up as an option in the widget options.
