Turn off Course Messages in Original Courses
These are instructions for original courses, for Ultra course instructions, click here.
Course messages allow students in your course to communicate with you and one another directly through Scholar. In certain circumstances, this may not be what you want. If that's the case, you can turn off course messages in your course.
To do so in orignal courses, choose Tool Availability from the Customization menu.
Scroll down to the Course Messages tool, and uncheck the box under Available. Warning: removing access to tools in this menu can cause problems in your course. ONLY remove access to the Course Messages tool.
Click Submit, and Course Messages will be removed.
