BuddyPress.org

This seems to be a more and more common request.
I am contemplating the use of groups (user groups), to segment users. And to make those “user groups” hidden, and a hierarchy of the whole site.
It could be described as roles, but within these ‘user groups’ I still require all the current functionality.
This problem may not exist if a privacy plugin, allowed control over some sort of ‘user type’.
