Personally, I think we should switch the contest to a kind of autonomous mode until the end of November. If nothing changes... then there won't be any point. But at least we'll be able to provide a prize for the winner for the New Year.
My minimum... is 15 submissions. Then there will be a real choice. And yes, my opinion isn't the final word, so feel free to share your own!
And one more thing: please submit the maps right away.
