Hey I've been thinking and maybe we could do like this; I complete the terrain of Kalimdor and then you fix triggers, units, players, and everything that will be in Kalimdor. Then I terrain Eastern Kingdoms and you fix units, triggers etc for Eastern Kingdoms. Because terraining this map is hard work, since I have to make it look like WoW and that's not as easy as you might think it is. And the work you're going to do wont be easy either, so instead of me doing all the terrain now and leaving you with lots of work we can do like this instead. Then I'll have a break while you do yours and you'll have a break when I start terraining.
This way everyone will be active and it will also be easier for me to change things, I'm quite sure that some things I'll have to change for you might decide that you want a boss place over there and a tower over there or something like that. And then when we're ~100% complete with Kalimdor we'll move on to the next continent and do the same thing.
