I was all set to post my own stuff there, but I see they want all my personal information first.
Perhaps I'm paranoid but I don't post my full name, full mailing address and personal email address on any website.
I have no idea how that info is used, what list it will appear on and who that list will be sold to.
It's probably perfectly innocent but personally I can't take the chance.
I see it's sponsored by
http://www.ucsusa.org/ which has a theory which I personally don't prescribe to.
