Hi Elizabeth,
Sorry to hear about your confusion upon signing up. We try to make it very clear that basic membership gives you access to additional content, but not all of the content. Specifically, the first level is free to the public, the second level is free to registered users, and all subsequent levels are available to users with paid premium membership. There's a full comparison chart here:
