Do what I did: post to Facebook, and put in your message that you're testing it out and this is just a test post, not an endorsement. Then wait for the email (mine took ~30 mins). Do this at late at night (like I did) and delete your FB post after you get the email (like I did). Alternately, you can go the whole +hn route described below. It took longer than the FB route, but at least you're not participating in marketing of a sight-unseen web service.
