Start your draft now

You’re nearing the finish line! As the submission deadline of September 5 (5:00 p.m. ET) inches closer and closer, now is a great time to at least start a draft of your submission if you haven’t already done so.

Start your draft here

Give yourself the next few days to carefully review all the requirements and make sure you’re not missing anything. And for good measure, review it all again one last time. You’ve worked so hard to get to this point — don’t let a small omission trip up your entire submission.

Review the submission checklist and make your submission the best it can be.

Just getting started?
