Not to make anymore work for people
But since there will probably be some kind of short list before they decide the final ten, would it be possible to notify the other short list people that they indeed "came close." I'm not talking some wonderful little critique of the submission, just a slightly different form letter that says, "While your work was good enough to make the short list, you unfortunately were not chosen....". Call it a consolation prize, but at least some people would know that they were on the right track.
