OK, so the wiki is meant to be a community tool really. It's not intended that I sit here and populate the entire thing. However, in order to get it started, I'm happy to write a few articles.
What would people like me to write them on? I'm going to start with something on the Terrain Editor as I think it's a shame nobody has done any mapping yet (maybe I'll create a new subforum for it), but what would you like after that?
