Activity Roles enable you to describe the role played by a given attendee with regard to an activity. Typical roles may be, "Host", "Greeter", "Facilitator", "Bartender", "Usher", etc. They typically represent things people "do" at an activity.
Note: You cannot delete a record that is in use. One solution is to create an entry called, "Undefined" or "Unknown" and merge the unwanted entries into that one.
