IMHO, the main problem people have with the AMA is that it is so very difficult to get a response from headquarters. It would seem just out of common courtesy, they would reply to emails.
Then again, I can understand that they must receive tons of email everyday and perhaps most are complaints from members who will never be satisfied with any solution coming from anyone in the AMA.
Take care,
