To be able to create your own courses, you must have been assigned the rights to create courses (role: course creator). This is done automatically.
If you have the rights, you can create your courses in the course areas of the current and next semester. To test features or ideas, we provide you with the sandbox course area.
In the relevant course area, click on More → Add a new course in the top right-hand corner to create and edit your new Moodle course.
