Membership registration form not displaying

Hi,
I'm trying to use the Membership plugin (2.1.4) on WP-Multi-site (3.2.1), theme Twenty-eleven 1.2 on newsitetemplate.theimpactaward.org. I've set up my Access Plans, Subscription Levels and Payment Gateway (Free Subscriptions), Membership is Enabled.

When logged in as admin my Registration page looks perfect, like this:

When not logged in (as a Guest/Stranger would see it), the Membership form is gone, like this:

I would like guest to see all the membership options and to use one for sign-up.
Thanks,
Chuck S.
