Can I say something?
I thought this was pretty terrible. Trust me, I wrote a tut on modeling (It is in the graveyard because all of the picture links broke) so I know a tad bit about modeling, but even to me, someone who has some idea on how to use these tools and knowledge on geosets and stuff, this tutorial is absolutely mega-confusing. I think it classifies as a tutorial, but I think that it needs to MAJORLY be refined. Especially in the areas where you just attached random posts at the end of the tut. On those you completely lost me on a lack of explanation. Don't just show how to do something, but explain why you are doing something as well.
I give this 1/5 for lack of effort and explanation.
Seriously Terrible. I expect better from you.
