To be brief, I have Googled this problem and also followed many instructions I have found on Adobe's site, and not one thing I have tried has gotten me UNsubscribed from Adobe Reader forum email notifications. Many of the "Googled" results are many years old, and the screen shots don't even match the screens I have in Windows 7 Pro. It is impossible to follow some of the instructions provided, as the descriptions within also don't match what I'm seeing on my screen. Meanwhile, I am receiving hundreds of emails about forum activity, and if I just delete them, they somehow reappear in my Inbox.
Does anyone please have up-to-date instructions for UNsubscribing, that really work ??
