@peter jeffrey cobb,
Just as an FYI, they sign up for sites like, or take "Surveys" that require an email address, you're opening yourself up to being put on mail lists that are sold to other companies. I'd suggest creating a second yahoo account strictly for that kind of thing. I have a "Junk Mail" account and whenever I have to sign up for something, that's the address I use. It helps keep my personal email free and clear.
Good luck!
