How can Students use the Messages tool?

What is the Messages tool? The Messages tool is iLearn's internal email system and can be used to communicate with instructors and other students in each of your courses. Each course site has its own Messages tool. The Messages tool is like email in some respects but with two fundamental differences. The Messages tool does not use external email addresses. Instead, you simply select the person you wish to write to from the list of enrolled site participants. Also, messages do not leave the system. They are not carried over the Internet like email is; therefore, they remain self-contained within the course or project site.
