Hi guys.

I've seen a lot of maps on TMX that contain the tag "Signature". What exactly does "Signature" mean?

Thanks.

It comes from the Weekly Race competition, where Signature was one of the map styles someone could build in.

This is from the style description given when uploading a map:

Signature
No style rules. The author builds a map following only their own creativity. If the author has made many maps, the map is probably recognizable as being from them without even looking at the author name.
