Making Members Profiles Public (opt-in process)

We need to implement a way to make members profiles public. The way of doing it is through an opt-in process whereas members will decide if she wants her profile "public" (meaning, available from outside the CC Network) or private.

There is consensus over the opt-in process on the ExCom, and that means we don't need to change our privacy policies.

Maybe it worth using the opportunity to ask them to complete their profiles.
