The Reykjavik City Education office runs the Moodle installation, http://netnam.reykjavik.is
We are using Turnitin Assignment2 for a limited number of students, and consequently paying a license fee for that number.
Recently we have noticed that other courses, not using Turnitin, are counted among active users. We have been searching for solutions, which could possibly be traced to unusual use of Moodle.
We have given the role "question sharer" to a number of teachers. Is it possible, that using a shared question bank from a Turnitin-type course in a non-Turnitin course could lead to an association, so that both courses are considered Turnitin courses?
