Users can make choices as to what "grade" they give their personal information. 

Public - Anyone can see it

Members Only - Registered Users and Admins can see it (anyone else?)

Admin Only - Only members of the Adminstrators group can see it.

That's cool. But how do I apply it? Are there any built in apps in DNN that take advantage of this? Could someone let me know where in the database this information is held, in case we want to create a member list of all our registered users?

TIA.
