I've posted a journal entry on DA to get the ball rolling.

We will need:
-3 or 4 prize donators. Each prize donator will make a prize for a certain place. So we need someone for 1st place, 2nd place, and 3rd place. If we have someone else who wants to be a prize donator, they can make a prize for Honorable Mention.
-3 judges. I will be the 4th judge. At the end of the contest, each judge will pick either 3 or 4 entries that they think should win. 3 if we don't have Honorable Mention, 4 if we do. I'm allowing each judge to judge in their own way without a certain criteria, as long as there's no "I don't like you, so your OC sucks" or whatever.

If youre interested, please post your DA username.

OrangeDragon is going to be holding a contest on deviantART that will involve, as the title suggests, creating a Skylanders OC. Here are her guidelines for the contest:

Since it will be held on dA, it is possible that a member of this forum might not win, but if someone does, they will be given a prize of a yet-to-be-determined amount of gems. We will also need judges and people who would be willing to donate prizes; this could be anything from drawing the OC or another character of choice for the winner to dA points to banners or avatars. Additionally, to submit a character, you must take this Mary Sue test and include your score with your OC. Don't lie about your score, though.

Post here if you're interested in entering, judging, or donating prizes to give us an idea of how many people will be interested. You can also ask questions here.

Edit1: Changed the Mary Sue test link.
