No, I don't think this in anyway an actual contest. I just think it would be fun to do.
Basically, all you have to do is post a month below that you want to claim, before drawing your character in a pin up sort of fashion. Please check on the list to see whats acceptable for each month. You can post other ideas for that month, but most of the themes or topics are pretty vague. So be creative!
Pin up means underwear, swim suits, sheets. Just don't expose anything. Keep it deviantart friendly!
There is no template, but if you want you can put the days of the month you choose under your picture to add authenticity.
