Joe explains things clearly and well. He links things to the real world by using his personal experience of how he did exactly this for a customer. And on top of that he makes the webinars both interesting and funny so that I don't even notice that I am learning/refreshing the information. I tune in as often as I can to his Monday evening sessions to keep my knowledge up to date. But do you know the best thing about these webinars? They are free. Once you have taken (or signed up to take) one of the courses, then you get the access to them. It is an invaluable resource.
