Yea that FAQ surely needs some clean up. I'm thinking of delete/reformatting/overhauling that whole section. It was more a joke than anything.

Thanks for the feedback. The site is pretty stable, and we don't use the addresses for anything but birthday reminders. Feel free to sign up already, and just pm if for some reason you'd like your account deleted.

The odometer itself is more of a novelty. It just counts the days everyone has been alive and displays it in an amusing fashion. The birthday-email-reminder script is where the practicality is at.
