BuddyPress.org

Hi, I was wondering if someone ever did this before. I want the Group Admin Users to publish in the Group’s name, so that the users do not know which person is behind the group. For example:

The Group called “WordPress Developers” has the user “John Doe” as the admin. When John Doe posts an update, I want that in the activity stream the published item appears as “WordPress Developers posted an update…” something like that, can someone point me in the right direction of how can I achieve this?

THANKS!!!
