Users of Dribl sometimes get registrations and members confused, thinking they are the same. However, the two are different. Registrations are a single representation of a person registering against a product offered by a club. A member is the actual person, regardless of all the different registrations they have registered for over time.
Members are created through the registration approval process. When a registration is approved, Dribl will reconcile and create or update a member with the most up to date registration data.
