Greg,
If you join their "Modeler's Club" you will also get the e-mails.
Only one e-mail per month and I cannot attribute any SPAM or sell-off's of their mailing list to the membership.
Seems like a pretty clean "risk" for those who are worried.
You'll get the monthly announcements a few hours before they post them, plus some narrative that never shows up on the web site.
I, too, have deleted mine from this month. As a dealer I have the printed version somewhere, but I'm down and out with back issues -- surgery on Wednesday!
