The new WordPress admin bar is much prettier than the default BuddyPress bar and so you will be pleased to know that the two are being merged. The BuddyBar will be removed completely in a future release of BuddyPress, but you can ditch from version 1.5 if you wish.
To Make BuddyPress Use the New WordPress Admin Bar
You can Add support for WordPress’ Admin Bar by setting BP_USE_WP_ADMIN_BAR in wp-config.php.
/* * Make BP use WP bar */ define('BP_USE_WP_ADMIN_BAR', true);
You can see this in action on our Pure theme demo site.
