I see several mentions of the NotAMemberError happening on unsubscribe but I am getting it when adding a member to a list. In my case we had a list of people that just one person was an issue. As it turned out that particular person's email address was a misspelled version of someone that is already a member of other lists. For the sake of example we can call that person's correct email is wwwrong@domain.com which takes fine and is already an established user. When you try to add wwrong@domain.com the error comes up. I have been unable to duplicate except that one exact example and another slight misspelling. Thanks for any help that I can get in advance.
