I just saw this post and visited the link.  After cruising through the site it appears that it is probably a good course. Online courses are quite good these days at technology has enable very good online presentation and interaction for instructors and students.  The thing you want to be aware of is what is their basis for the instruction - do they do correction, positive reinforcement training, physical correction - basically is it just theory based on a method.  Nothing wrong with it but you must be aware.

Seems like a good choice as a place to learn the basics and then put it into practice.
