Need to know: How to Delete Courses/Classes in Learn Center

Content

Where can I see all the 'courses' or 'classes' that are in our Learn center? A little trial and error has left me with a several of the same name that do not come up in the Course listings. All I can see is one or two to delete (no master list per say), but if I pull up the insert or copy course/class screens I see many in blue and red (course/class). Any ideas? I am working to get our first wbt class distributed and some parts are clear as mud. Thanks in advance!
