Although this may be a short thread, I just wanted to give a little tip. When experimenting with the XML and stuff, make sure you have absolutely everything on the map. You never know what might disappear and what not when you're working with the XML. Not putting anything on the map might cause you to miss out on the chance of a wonderful [could have been] discovery. As a map maker myself, I like to do this. And a few times I actually have discovered a decent trick which I'll probably reveal sometime in the future. Just a tip.
