maybe I missed something but not sure I got what presenter was promising. But, I am really curious and may follow up with subsequent courses.

Although the presenter was knowledgeable about the subject, the form of presentation was unsatisfactory. He used small white boards with handwriting on them that could not be read on the screen. It would have been better for him to have someone prepare a Power Point presentation which would have been visible to the viewers and the attendees in the room. Finally, Mr. Graff's attempts at humor were poor as well as uncalled for during the lecture.
