dJulkalendern opens up for guest submissions

dJulkalendern, the yearly advent-CTF of Datasektionen, is inviting anyone to write a guest window (guest challenge) and still be alowed to compete. The window shall be made according to instructions and emailed to [email protected]. The dJul-team will then look at all submissions and decide which will be included in the contest. The better your submission, the higher the chance of us including it, and you will still be able to solve it for cheap points! We will however not inform you whether your window was included or not, and we reserve the right to modify it as we see fit. The guest authors will be credited after each window is solved, and at the end of the contest.
