I think I see what your talking about as my says the 12th also, but I think it's just for the Silver membership (I think that was a limited upgrade a while ago).

As far as I know I've never gotten an email stating that they would cancel my memebership or get rid of my pictures...I would definately be po'd if they did since I've been a memeber for about 3 years now and have thousands of pictures uploaded there!
