BuddyPress.org

I have a site where I really don’t want other members to have the capability of “reaching out” to all the other members… Forum boards are okay… But I don’t want anyone to be able to go in and send everyone a message individually. I’m in a business where clients can be stolen. I saw something that said BuddyPress has a “Member Directory.” Can this be disabled if it’s on there, and if it is, is it sort of going against installing buddypress at all? I just don’t want people having the capability of contacting everyone else. In the forums I can just delete an inappropriate post. But if they can just mass email or email members 1 at a time, I’d like to avoid that. Thanks!!!
