You can cancel your subscription directly from the My Subscriptions tab at the top of your user profile (click your avatar in the top-right of every page to access your user profile).
If you'd prefer us to process a cancellation for you, submit this form. You'll receive a confirmation e-mail.
For security reasons, your request will only be processed if the email address submitted with your cancellation request matches that in your ISDC profile.
We'd welcome any feedback you have - please add it in the message box.
