However, they've sent out email asking for referrals of "male consumers 18 years of age or older".
If you meet those criteria and are interested, drop me a comment here and I'll forward the invitation email. (Rather, I'll forward it to anyone on my Friends list and will consider forwarding it to other respondents.) There is no guarantee that they will take a given applicant, but I will mention that I've never had any privacy concerns about them.
