<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>
