It's great to hear from you again. When I saw the feature on nospronos, I thought that maybe your authentification strategy was not giving good enough results. Sounds like I was wrong.

Did you try to know why they wanted a real account in the first place? Was it because they kept loosing their secret URL? If yes, a resend feature via email would have done the trick.

Anyway kudos for the website, we are having great funs with our (mostly wrong) predictions.

Did you try to see how close from reality have been your best user?
