+ Referral: + +

+ What is this? +

At exactly 00:00 CET on 1 Jan, the system will choose a random entry. Their referral key shall be publically + displayed on this page. The person associated to this referral key shall contact us with their private key. + They shall win a little prize. To have one's entry weigh more than the rest, one shall have to spread their + referral key amongst the people. Every referral shall increase their chance of getting selected.

+ How does one enter? +

One needs a referral key to enter.
