I saw that too, but I was afraid it was something you had to cancel within 30 days (and I have been known to forget) - were there any requirements to cancel or they would charge your credit card for something?
No. I didn't have to give a cc# to join, so they can't charge you if you forget. It says they'd email me to see if I wanted to join for real. I figure it's safe if I don't have to give cc#.
