"Mapmaker 2014" Contest

But someone could suggest a map from another resource, and then create a topic on the forum, and it would already participate in the contest.

Until the 18th – please, I will gladly add to the archive with maps from other resources that participated in the contest. In this case, it would be appropriate to use the archive as a repository for contest maps and simultaneously for maps from our forum over the past year.

But there is a problem with maps by one author. They can take votes away from each other, and as a result, a third one will win.

I didn't quite understand the problem. We are voting for the map, not for the author. If a person made fifteen average maps, and another made one, but a very good one, it is not surprising that he will win, even though the first one could have scored more votes in total.
Besides, this issue only applies to two participants in the contest, so it is up to them to decide, not me.
