I come back to Zbrush from time to time and I must say that when it comes to teaching the basics, Pixologic and all of the very talented people putting together 'tutorials' on Central are not actually teach beginners the basic. This is particularly the case with hard surface modelling - open up any hard edge 'beginner' tutorial and you're almost certainly faced with some hugely complex object. For example, where you should be starting with a cube and build up a complex object from that basic form, you may see a finished tank bristling with dozens of bits and pieces, or something equally complex. What beginners need to know is how to start with a simple form such as a cube, how to modify it and build on that, discovering along the way how to add various other objects that may or may not be part of the base object. Thus you're learning the interface at the same time. The way I see tutorials here is that it's already assumed you know all of the basic stuff and are totally familiar with them even though the tutorial may be aimed at a complete novice. I have news for you all of the would be teachers out there, beginners don't have a clue what's going on and they are not really interested in 'teachers' on an ego trip who are more interested in showing how clever they are using the product rather than imparting useful knowledge. Each step needs a full explanation of what the intention is and how it will be achieved; all I tend to see are demos of 'this is how I do it.' If you can't work at the KISS (keep it simple stupid) level, you might as well not bother with beginners. Don't demo - teach - there is a difference.
