Instructors can control the availability of tools and also decide which tools Guests
and Observers may access. The tools that are available by default are listed in Course
Tools and can also be added as links to your course menu via the Tool Link option.
There are tools that are not available by default such as the Sign Up List (which
after activated can be accessed via Interactive Tools). You may also limit access
to certain tools such as Email and change the default settings so students can only
email the Instructor and not have access to the other Send Email features.
