May I share the course materials from Mike's in-person class?

Course materials are copyrighted and were provided for your personal use. But you can share them with your immediate team. We don’t want to put a specific number on that but please be reasonable with whom you share them. 

The main thing you cannot do is use them as the basis for your own full training course. If you are looking for something suitable for that, we have this presentation available in PowerPoint, Keynote and OpenOffice format: https://www.mountaingoatsoftware.com/presentations/an-introduction-to-scrum and you can use it as the basis for a training session.
