Create a map with a tutorial on how it was made
I mentioned this idea quite a while ago and quite a bit of talent here and some excellent tutorial authors. What I propose is a monthly mapping challenge where each entry submits a final map in the opening post and then detailing in tutorial form how you used application X to get to the final map. The idea is that it would give our mappers a real challenge of writing up your process and carefully explaining how you use your particular software of choice to produce the final map.
For those who have previously submitted tutorials that take a map from start to finish, we would like to see a different style/artistic approach taken to the challenge map so we don't just repeat the existing tutorial.
