Good Question Alex! Life has intervened since I made my statement about the tutorial.
First though, to submit the entry you'll just email it to me. What I envision is for you to save your design as a jpeg image and to write a description of your design (your vision for the course, any hole strategies you want to call out etc.) in a word-processor.
Now, there's no way I'm going to get a tutorial done for this thing, so I want to find out who needs help, what kind of help people might need, and adjust the due date if necessary. If you've put in a bunch of time and are not quite ready, I don't want to cut you off, we'll get something figured out.
So anyone who's having trouble, post here and let us know what the issues are. It's likely that either I or another competitor will have an answer to the question.
