The recipients you listed will receive an invitation email from Learning Catalytics. Clicking the email's Accept this invitation link opens Learning Catalytics, where a recipient can log in to receive access to the course.
The exception to this is if you are sharing a course across two Pearson accounts that share the same email. (See below.)
After your colleagues accept the invitation, your course appears in their My Courses list.
From there, your colleagues can edit any settings or features of the copy, make copies of the copy and edit them, delete any copy, and copy modules from the course into their own courses.
If you select Share course again, you see the names of everyone who has accepted your sharing invitation. Select Share this course with another instructor to invite others.
