Hey! I have been practicing the editor for quite some time, and I would like to direct everyone to Bockerboy.webs.com.
I've started a 'business' if you so call it that. Check out my latest map that I made. They are free, and the community on that website is friendly and easy to use! I have a couple dozen more maps and missions on the way, as good of quality as the default missions that come on the game.
