If you have an active account with TuneRegistry and you register registrations while with us, the registrations would still remain with the organizations that we delivered your registrations to even if you cancel.
However if you decide to terminate your membership, you will no longer have access access to your TuneRegistry account and will need to make changes and/or modifications with each society individually.
