This Christmas you can be the one who will provide a Christmas background for our wiki. All you need to do is go to the link below and submit your idea.
You still don't have any idea? Don't worry, you can check the page for current submissions and get some inspiration.
If you don't feel like doing any of above, you can vote for already submitted background and also give a very valuable contribution to the contest.
The contest will end at midnight EST on December 7, 2013, so don't pass the opportunity.
