Prolific BuddyPress plugin author etivite has just released a plugin that automatically creates a group for administrators and moderators.
BuddyPress Group for Community Admins and Mods creates a private group where all current group administrators and moderators can interact. Once you have this group in place, you can send out announcements to your community support staff. You can even give them a forum of their own to maintain community standards or just to blow off some steam.
Download BuddyPress Group for Community Admins and Mods from the WordPress plugin repository.
