How do you win? By submitting previous work of yours that is judged by their editorial team. The catch? rights grabbing terms and conditions:"

8. You will retain full ownership rights in your submissions, but in submitting your submission to us, you agree to grant to us a worldwide, exclusive, royalty-free, transferable licence (including the right to sub-licence to any user of the Website or otherwise) to use, reproduce, distribute, prepare derivative works of, display or otherwise manipulate your submission including for the purposes of the submission. In submitting your submission to us you agree to waive all moral rights in your submission.

So in other words give them your word for free and they can use it however they wish!!!
