Initiative Q is an attempt by ex-PayPal guys to create a new payment system instead of credit cards designed in the 1950s. The system uses its own currency, Q, and to make people start using the system when it's ready, they allocate Qs free to people who register now (the amount falls as more people join – so better to join early ). Registration is free and they only ask for your name and an email address. There is nothing to lose, but if this payment system becomes a world-leading payment method, Qs can be worth a lot.

This link stops working when I'm out of invitations. Notify me after signing up, because I need to confirm you at the end.
I signed up 2 weeks ago. So far, no spam email. I think it's legitimate. Will it actually come into fruition? Who knows.
By the way, if you play any good jigsaw apps, please let me know.
