When a user clicks "logout", present a pop-up survey before logging them out. Store results in Moodle data infrastructure. Allow user to say "don't ask again" and then don't show this to these users again.
View attached PPT as full-screen for a mockup of the functionality. In addition, we want to define the system roles of the users who will see this pop-up. If the person is not in a selected role, then they should not see this survey.
