I signed up for a membership a few months ago and was just charged again.

As indicated on the “Join” page when you subscribed, your membership subscription automatically renews at the end of each term, and there is no fee increase for as long as you remain a member. You may cancel or upgrade at any time. Cancellation of your membership is done via PayPal or "Manage My Membership" via the Click Community forum. Sorry, no refunds on previous subscriptions.
