Actually, you have. As a service to the many members who have requested this, our subscription plan under PayPal runs on a system of automatic yearly renewals. You agreed to having your subscription renewed automatically when you signed up. You can read the terms that you subscribed to here.
HOWEVER... you are not obligated to renew your subscription. Simply log into your PayPal account and cancel your subscription there, even if your year is not up yet. This will not affect your subscription to our website until the actual date in which it runs out. Just continue to log in as normal. When your year is up, if you have not renewed, your account with us will then be suspended.
