Ok, well I'm not just going to post someone's mom's/dad's address on the Internet. Sure, you could probably find it with one of the many search engines out there, but maybe you aren't that smart.
So, I have to make you work at least a little bit for it. Fill out this form, and hit Submit. The address will be emailed to you, so make sure you use a valid email. Also, if you want to be reminded about the upcoming mailing, click the checkbox and you'll get the Postcards Project Newsletter (only once a month). If not, that's fine. No email address will be sold/rented to any other human being. Aliens, maybe - humans, no.
Finally, thanks for your help. This is a really fun project and I look forward to more crazy memories, thanks to you.
