Frankly, I don't really know. Maybe you're just so special that your posts simply have no choice but to appear in my email inbox. ;O)
When I go to post into the edit box, at the bottom I see: Reply - Reply to Author - Forward - Report span - Rate this post ***** - For the past few years when I or others click on "Reply" it posts to the forum only, and when I click on "Reply to Author" it sends to the author of the post. Seem pretty straight-forward to me, but perhaps it's just groups.google playing tricks on us, or maybe just the way that different browsers show the options. It's not a big deal, but I have only seen posts coming to my email address from you and the other dude who was posting for awhile and seems to have come and gone, as predicted. I enjoy checking in and posting to the AZ forum, but don't really want to get any more emails in my inbox than i already get. I'm not really making a fuss, as it doesn't really matter much to me. It's easy enough to filter out emails from AZ as spam, but I'd prefer not to. "It ain't nothin but a thang. It ain't nothing but a thang!" (Obscure "Hamburger Hill" quote."
