As an instructor, you can copy individual discussions in one course directly into another course in which you are enrolled. You can also send discussions to other instructors at your institution. When you copy a discussion, any assets within that discussion (images, files, etc.) will be included in your discussion copy.

Notes:  

• To share course content, you must have the Course Content - add / edit / delete permission enabled.
• Shared content does not count against course or user quotas.
• If you copy the same discussion to the same course more than once, the discussion you previously copied will be overwritten with the newly copied discussion.
