Shaak, if meant a list of contest rules, then no, nothing additional that wasn't mentioned in the first post. If you meant designing do's and don'te as a graphic designer yourself, I'm sure you already know all the basics that Master Durangus mentioned. And I'm sure that if MD was reading this that meant he wanted to show us his skills by entering himself.
IF you want to enter, but feel that your skillz are lacking, why not team up with someone with more knowledge? If you have a design that you want help with, feel free to post it, and then ask the community for help. You can do anything you want, post as many times as you want, edit your submissions all you want UNTIL MARCH 15, 2012. Then you're going to let the chips fall where they may.
Until then, good luck to everyone!
