To be honest, heck, I used it maybe 1500 days or so before registering. Then again, at first I was in school, and then for a while after that I had no Credit Card, and I was even more cautious about PayPal. It bit on me more and more, sure. A one-time $20 contribution for 3 registrations is a deal for such a feature-filled program, to the point where I broke down and bought my code the moment I got a Mastercard.
