While this chapter describes the effects of different configuration choices, there is no substitute for experiencing them yourself. Don't be afraid to experiment with different settings. You can try this method:
Install two different browsers in your computer. For example, Internet Explorer and Firefox.
In one browser, log in as an administrator. Go to the Site Administration menu, and experiment with the settings that you read about here.
In the other browser, go to your site as a user—an anonymous visitor, student, or teacher. Each time you change a configuration setting, refresh the user's browser and observe the change to your site.
Sometimes when I'm configuring a site, I use three browsers at once (Internet Explorer, Firefox, and Opera), and log in as a site administrator, teacher, and student. Then I can immediately see the effects of my configuration choices on the teacher and student experiences.
