The following function puts a tab in the admin menu (this as a submenu under the profile.php) and that allows a url to be directly linked to it (as opposed to being launched from a admin page)
function admin_menu_new_items() {
global $submenu;
$submenu['profile.php'][232] = array( 'Menu item name', 'edit_posts' , 'http://google.com' );
}
add_action( 'admin_menu' , 'admin_menu_new_items' );
So now just have to load the <code>bp_loggedin_user_domain().'profile/'
