Regarding the contest.
It's unlikely we'll find 15 participants.
This activity isn't very popular among us...
I'm not against extending it until 2012, but that's too long. We could drag it out for 100 years...
Let's just make it an internal contest, using these maps, if there are problems with an external one. But I don't see any reason to extend the submission deadline.
++++++
P.S.
The deadline has passed. Everyone who wanted to submit their entries has done so.
