How do I sign up for this?

I have my game made (Just started on it 5 days ago), and I want to take part in this. What do I do? Do I attach my game and code here as an attachment? do I email someone? There was nothing about how to enter on the website: http://www.java4k.com

If you create an account on java4k.com and log in then a link will appear to submit a game.
