How do I share my Lt Lesson with a colleague?

There are 3 ways sharing an Lt Lesson:
1. Invite your colleague to the Course that contains the Lesson (to do this, go to Staff Accounts > Invite within that Course) to grant them access to your Course
2. Select use the 'Copy to Course' option and copy the Lesson to a course that your colleague already has access to (Lessons > Lesson of interest > Gear menu)
3. Export the Lesson (Lessons > Lesson of interest > Gear menu) and give the resulting .kura file to your colleague.
