I was trying to duplicate my work into other courses I was setting up in one workroom. I didn't know how to duplicate my course, so I looked it up and it said to cross-list it. I followed the instructions and now my original course with all my work has disappeared and my other courses don't have any of the original material I created.
I will be happy if I can get back my original content.
Then, how do I duplicate it for 4 other courses?
