Out of the blue I got an email from greatfunsite saying that I had signed up for their services. I knew that I hadn't signed up for anything like this, so I called the 800 number and canceled my membership. While I was on the phone with them I asked how they got my information. They said they got the info from classmates.com, which is surprising considering I don't have a membership with classmates. I'm still not sure how they got my personal information, but hopefully there won't be any problems with my cancellation. It's unnerving that they can mine your information from other companies and sign you up for a subscription service without your knowledge.
