For those of you who will be creating teams you will probably want to create a team flag/logo to help promote your team. So to help you get started here is a template image that you can use to get started with your team flag. Flags must be submitted as 72 x 48 .jpg file.
And to help give you some inspiration here are a few of of the team flags from the last competition.
Enjoy, good luck and have fun!
