Depending on what type of payment schedule you have chosen, your subscription will become inactive on the first day after the cycle that you have paid for. Subscriptions paid by credit card are automatically renewed unless requested otherwise by the account holder. Therefore, as long as your information is current you won't have to worry about re-subscribing. If you ever want to know when your subscription is set to renew, just click on the "Account Info" link that you will see after you login. You will then see a page that will let you know all of the information associated with your subscription, including your expiration/renewal date.
