Assign specified non-admin users the right to manage company contacts which will synchronize to all users.
Users are always asking to share their contact let's with each other. We should not allow end users to administer users accounts, but it would be convenient to allow one or more select users to manage a shared contact list that replicates to all users.
An alternative would be the ability to flag contacts that become part of a shared pool which synch to all users. On the receiving side you should be able to decide if you want to accept these Shared contacts or not.
