How do you go about unsubscribing from extra subscriptions to WCM? At the end of the magazine it says this:

WinCustomize Magazine is a monthly magazine that is sent to WinCustomize users. If for some reason you do not want to continue receiving this magazine, visit https://www.wincustomize.com and in your account settings uncheck the "Receive WinCustomize Magazine" option.

That's all well and good if you want to unsubscribe from your current registered address, but what if you're getting it at more than one address, and you want to unsubscribe an unregistered address?

I know I could probably take care of it by changing my registered address a couple times. I could also just put a kill filter at the email server of my second account. However, I don't think either of those solutions is real elegant.
