I tried Backup & Recovery 2011 (Advanced) Free and it wants Registration information so that they can spam me. Please note:
We send our exclusive offers 1-2 times a month.
It says on that page also: "If you don’t like our messages, you’ll be able to remove your address from the subscribers list at any time."
and this is an opt-in option. If you don't mark it, you won't get messages.
I don't get any, and the product is great.
