If the Applicant has selected the Reference from the dropdown box at the reference request question in the application, the Reference will not receive separate reference request emails for each Opportunity for which they are being used as a Reference.

If the Applicant has entered the Reference separately each time via the "Add a new Reference" link, regardless of whether the Reference was already listed in the dropdown box, the Reference will receive a separate reference request email each time this has been done.  

NOTE: If the same reference provider is chosen for the same reference questionnaire type, the reference only has to submit one reference and all of the requested references will be updated and also be submitted, saving the Reference Provider time.
