The Classes tab allows you to:

• View the list of users associated with a particular class
• See the names and ID numbers of each participant, as well as their username (if you are a supervisor)

When you click on the classes tab, it will look like this (Why doesn't my screen look like your screen shots?):

To view a class, click on the link with its name. That will take you to the following screen:

This page will tell you the class name, the URN associated with the class (a unique identifier), a description of the class, and then provide you with a list of members. If you are a supervisor, it will show you the names and IDs of each user, but if you are not, it will only show the list of usernames.
