Your Siminar will look very similar to end users as it does to you when you are not in edit mode. The only difference is that participants can mark content as "done" but you can not as a facilitator.
If you want to get the full experience that a real participant would, we suggest creating a test account using a different email address and then enroll in your course. This will also let you test the email notifications that the system sends out. You can also use this account to test any scheduled Siminars you create.
