Remove me from your mailing list

I once opted out of junk mail via a form on the Direct Marketing Association website. The DMA is now called something else and don't know if it's still possible to opt out. You had a relationship with the Good Sam enterprise; they'll not forget you. Like junk mail, it won't go away. Hell, I still get occasional mail for my mother, deceased 26 years, my father, 21 years, & my oldest sister, 10 years.
