This is the 3rd of several 5 minute screencasts that teach you how to manage a Joomla powered site. I have a PDF document that defines the different user types in Joomla. Email me if you would like a copy. The screencasts lost quite a bit of clarity when I uploaded to YouTube, but the original screencasts are crystal clear. I do have a membership support site where the screencasts are crystal clear. But my intent was to offer them for free on YouTube as well. I apologize that they are not as clear here on YouTube.
