JOE, You were right! I really enjoyed these live lectures online, 1 hour felt like 5 minutes because he got my attention all the time, Mike Sable did a great job, it was easy to understand what he convey, funny too and never boring. I clicked on a PDF file that showed up after ending the course and got a certification of completion of the course. Ok, whats next? Have a nice day! Hans Egil Boe- October 14-2013
