BuddyPress.org

Hello first sorry for my english. It´s posible to display the groups to send private message? Ajax loading my users but not my groups to send message. I used the Mass messaging plugin but the problem is when i send a message to a group.
The message is sent to each of the users but not added in copy to the rest . The reply does not get the answer to all users, only the user who wrote.

Thanks everyone
