I used to live in Massachusetts not too long ago. When I was there I filled out these postcards for reducing junk mail sponsored by the Department of Environmental Protection.
It was a great big help, I even helped my parents. You know when you get junk in the mail you dont even want to open it, and throw it right in the recycling bin.
Follow this to the last page, its great directions to fill out your name and send it to each of the associations...
Thought I'd share.
