When you sign up a unique URL will be given to you. Get 3 friends to sign up using your referral URL and ensure your spot in the beta.

Eww, a snowball signup scheme.

If we get 10 people to sign up under your link, then you get beta access and 10 people don't unless they can find 3 people to sign up elsewhere.
I won't sign up because I think it's a dumb idea from the devs.
At least let 3 people sign up using your link and then everybody else should sign up using one of their links, that way more people get access.
