Signing up for a course is simple. When you are viewing the ?Available Courses? page, you will notice that to the left of each course is an icon with a file folder and padlock, and to the right side of each course banner is an icon allowing of a pen. Before you are signed up, the course remains unavailable to you, as does all of its content (except for the description). To select a given course, you must click on the pen icon and agree to the confirmation window on the bottom left asking if you are sure or not. By accepting, you will then be prompted to check your email.
