I thought this as first also but they are just hidden 
What about digital tutors, is it any good ?
I have both Kurv’s and Digital Tutor’s one. Both are good and each complements each other if you are a complete newbie (like me). I like DT’s DVD because it is clear, consise and covers all the basics (plus using a refernace pic to model which prompted me to buy it in the first place). Details are covered by Glen Southern in Kurv’s DVD. And the amount of time spent in the project is a real eye opener on the power of Zbrush.
I downloaded DigitalTut’s package awhile back. Very good as an introduction to zbrush, even if the artwork being created is somewhat dodgy at times.
If you haven’t already, try googling “zbrush tutorials” to find free ones, also give it a try using google images too.
I would like to thank everyone for their input as I’ve been looking for an introduction to ZBrush and decided to go with Kurv’s “Get Into ZBrush”.

In my case I go with digital tutors, kurv s., gnomon in that order.
The gnomon tuts are good but some times the voice of that guy in (zbrush prod. pipleline) are toooooooo boooring, repetitive and sombie-like, It comes to my mind this song dont take it personal hehe, also that annoying windows sounds (asterix,critical,exclamation etc.) the voice volume are lower and need to increase the volume, to properly hear something, but that crappy windows sounds play at normal volume and just imagine what happend when one of that windows sounds played and my stereo and pc volume was near in the top…·"#~@€@·!%%&! at the midnight when everyone sleep … ( just right now im watching zbrush prod pip., disc2, lesson 3, 2:45 , :evil: !!! :td: :td: :td: ) , I plan to start learning maya but only for that detail I dont buy gnomon dvds anymore.
by the way if yur dont have experience wit ZB I recomend the digital tutors one, its more clear, also use newer version of ZB than gnomon.
and for all dt, g, ks, I never use the interfaces, only pass that and start watching the vids directly from the media directory. waste of time and effort to made that crapy user interface.
