If you were looking to brush up on your Revit skills...
JB points out that you can download them from the AutoDesk website for free here AutoDesk Revit Architecture 2009 and AutoDesk Revit Architecture 2008.
Autodesk in their wisdom didn't include tutorials with their software... I guess it didn't fit on the DVD.
Follow the instructions and you'll be on your way... happy Reviting.
