Guys... STL is right,

If you don't want be in the thing... then just don't respond. But the wording is kind of funny.

"If you haven't responded in any way to date, you will not be in the Directory at all!"

Does that mean if they haven't heard from you already, then you are out? Why do I need to call then? Could be a whatever to English translation error.
Opt out, and chill.

STL was wrong about one thing, this is a marketing thing. AMA doesn't care if these guys are sucessful at producing a publication or not. They got their payment. If they pull it off then it certainly won't hurt the hobby. By selling permission to call, email, or send you a card in the mail, they executed a soft approach. They leave it up to you to participate or not. If you give them more and they abuse it... it's your own fault not the AMA's. As far as AMA selling lists to outside companies... Well duh... get used to that. But then again, just how much information does the AMA have on you anyway? Even the annual membership form doesn't have anything more than basic info. I don't even think they have your SSN. So who cares if the AMA doesn't get anything from the sale of the directory? If they got $40k, then they got it for nothing... I'm proud of them for finageling such a deal.
