Once you've become an active member you may cancel your next billing cycle for the monthly Resource Center fee at any time after the first 6 months from the date of access. 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 the start of your 6 months and you won’t be billed your next billing cycle.  There are no refunds for any months you have already paid for.
