In order to ensure that questions are not overused, you can see how often the question has been used at your institution through two routes.
1) In the Quest Editor, when creating your own questions (may also be used to looking for questions in various banks)
Pull up a question item, and look on the Preview, clicking the history tab
What is reflected is who and when other professors at your institution have used this question.
2) When an assignment has already been/is being created
Click on the item, and the + next to History and Preview. This history will also show who and when colleagues have used this question on their assignments at your institution.
