I also thing that on-line classes sounds like a very good idea,but i agree with plaski.The tutorials are very helpful.So why should i pay 700-1000$ for a 1 month class?As far as the length of each lesson,i thing 2 hours is enough,since that is the average duration in every university.Moreover two times a week i thing is fine.As far as the subject is concerned i would say "character animation",since is one of the subjects that has not been covered that much.Lastly i dont mind whether is a two way voice communication or typing the questions.As a conclusion i thing is a very good idea.I am willing to sign up as long as the price goes a down a bit,say 400$ for a 10 student class.
