Resolution
Turnitin has been integrated with Moodle at Manhattan College since Manhattan College began using Moodle. Accounts have not been created manually since that time. Turnitin Instructor accounts are automatically created for Instructors at Manhattan College when they add a Turnitin Assignment to a Moodle Course.
If an Instructor doesn't yet have a Turnitin account, and wants to use Turnitin for something outside of Moodle, the Instructor should set up the account using the following approach:
1) Create a Turnitin Assignment in a course in Moodle. This will automatically create a Turnitin account for the instructor.
2) The Instructor can then log into turnitin.com with their MC email address and then do a password reset/forgotten password.
