From the Settings for [Module Name] panel in the Manage Course part of the Management Console, scroll down to “Edit Course Details.”
Allow Guest Entry – The default is to allow Guest Entry into the orientation/training. If you don’t want guest to enter uncheck the box. Don’t forget to scroll down to click save when you are done.
Guests are not tracked so they won’t show up on reports and they will not see any of the quizzes. In addition, if you have a survey, module or URL at the end of your orientation/training, they will not be redirected there as a regular user would.
