Courses block
From MoodleDocs
The Courses block lists and allows navigation between all of the courses in which the logged in user is a participant (as tutor and/or student). The block title shows as "My courses" and allows one-click access to a course's home page.
There is a also the option to list All courses... available within the Moodle site. In 1.6 this will display a list of course types and a click on one of the types will reveal all the courses in that catagory. There is also a search all courses option on this page.
A brand new user to a Moodle site, who has not enrolled in any course, will see the block title as "Course Catagories".
When a student enters an unassigned course using the course block, they will be asked to enroll.
