I am glad i could help ^^
i finished the terrain section of the tutorial, the last missing part from the previous version was other ways of creating terrain and tips, it is now included in the tutorial can be downloaded from the same link.
http://www.dev3cg.org/tut/terrain.rarthis is finished but not in final state, i will go thorugh it again and fix spelling and grammer mistakes, and soften the wording a bit. (if you see any grammer errors please pm me ;))
also i scrapped the basic modelling part of the MED tutorial, it got too complicated, i need ideas for basic modelling subjects. an easy to model and texture object idea...
