Yup, I had that idea in mind too. But then greed overtook. Had I suggested the idea, I'd have lost the chances of earning a few bucks! Then I thought probably they'd see what I present first and if they (public jury) don't like the design, throw open the contest to others.
Anyway, I suggest one year of hosting added to the winner's account, equivalent to his/her current account value. This should be a win-win situation in my humble opinion.
But going by both the points above, I will always be at loss!
