Once you've become an active member you may cancel your next billing cycle for the Resource Center fee at any time. You need to give notice of your request to cancel at least 15 days prior to your next billing period which occurs either annually or every 30 days from your initial signup and you won’t be billed your next billing cycle.  There are no refunds for any months you have already paid for.  Those members that have paid for a full year of access to the Resource Center may cancel the Resource Center monthly fee for the billing period beginning after the first year.
