Hello Edna,
Sorry for my late response. Yes, just recently affiliate system was changed to referral links. To use it you must be a registered user at etsdiscount.com. When you log in at etsdiscount.com you see "Affiliate program" on the left menu. Click on the link and you will get all the necessary information such as rules, your unique referral link and users that registered with your recommendations.
Best wishes,
Arthur
