CHC Users need to be friends with whomever they invite to this group. All providers need to request being a member of this group, so they can invite their clients. On this social networking site I encourage everyone to be friends with as many people as possible. New Users request to be friends with existing members of this group, (like your provider, who should be a member of this group). When accepted as a new friend, you can ask to be invited as a new user to this group.
