In database view, there is a "Description" field on the user record. This has been helpful to us, because we are a very large organization with over 50 active users. I need to be able to know who works in philanthropy (further, who works for each of our 4 foundations!), who works in finance, who works in information services, and who works at our hospitals. That way, I can much more easily audit our user list! (aka, I need to be able to quickly pull a list of our non-philanthropy users...those who work in finance, IS and our hospitals...to periodically email those users to make sure they are still employed at our health system.
