What MCPitman isn't telling you is that he's using the latest development version of MCW for 1.7.10 (Forge only) with a lot of new features and fixes . The official release will be soon but here's the latest development version (should be stable but since it's not the official release yet I've labelled it beta):
This is what I'm working on btw so I guess it's not offtopic!
*Btw, you'll probably need instructions to really be able to work with the customstructure features and smoothing areas etc. Don't have time to write them atm (sorry, soon!), but at least you can get a sneak peak of some new features.
