Very valid points Starsky, especially given her addictive tendencies, thank you.
The email she was using was her school email and she cannot get that changed. Her other emails have filters in place, and there was no evidence of those being used.
Phone number, OM would easily be able to get it from others in the program as a lot of them jump for meeting to meeting, but it will be more of a hassle for him to get it. Plus put more emphasis on the whole A's are not OK on W. I will pursue this route and see what else she can do, ask her AA buddies to not tell him.
Maybe a good thing to have on these forums would be list of suggested transparency measures?
