Same thing happened to me! I just checked my email and received one from "CH DVD club"
I know for a FACT I did not sign up for this club! It had my email address, my correct mailing info, but the email sent to me just had a "temporary" user id and password. There was no cc info listed under my account, and I have a feeling that this could be a PHISHING scam!!! Be AWARE!!!!

Tricia, you may want to put up a notice somehow to be aware of this email, and to warn people not to enter their cc info from this email. I've got a baaaad feeling about this situation! If there is any info I can give you to help figure out where it's coming from, I gladly will.
