<b>What is this?</b>
|
||||||
|
<p>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.</p>
|
||||||
|
<b>How does one enter?</b>
|
||||||
|
<p>One needs a referral key to enter.</p>
