When I teach people about Microsoft Office I find that the most common questions revolve around the Microsoft Office Ribbon.
Believe it or not many people still use Microsoft Office 2003. When they make the transition to newer versions of office they have to learn all about the Microsoft Ribbon. I have created a series of tutorials that deal exactly with that subject. The first tutorial below is just a brief introduction and future tutorials will go into more detail on individual tabs within the ribbon. Enjoy.
