If, a member of AA drops my name to another AA member I don't have a problem with it.
I've had people outside AA I've told them to give my number to a family member or friend with alcohol problems.
I do understand with your profession it would be wise to keep your anonimity.
That being said, no one is supposed to mention a person's name they saw at a meeting.
At this stage in my recovery, it's not a concern for me.
