You can manage/review your course(s)/ or project(s) from your dashboard by clicking on "projects" or "courses" from the toolbar located at the top of your landing page, or click on the button titled: ManageProject/Course Matches. (Be sure to scroll down to the bottom of the page to see all options.)
Also: You can find your project(s) or course(s) by clicking on "outgoing requests or incoming requests" to see all of your requests attached to your course/ or project. Click on your project(s)/ or course(s) link and select the edit icon (shaped like a pencil) to update/edit your course/project, or the trashcan icon to delete, or the archive icon.
Note regarding DELETING/ARCHIVING:If there has been activity on your selected course/or project, then you cannot delete it, but you can archive it—which will make it inaccessible/invisible to everyone but you. (Again, make sure to scroll all the way down to the bottom of all pages you click on to see all options.)
