Membership Plugin - I am confused as to how the Register Page works

I am a bit confused as to how the Register Page works as I have never been able to 'view' it even as Admin - right now all it contains is the [subscriptionform] shortcode which I can see from the Page Editor but if I try to 'view' the page then it redirects me to Member's Home. Even if I "View site as: Visitor", I am still unable to view or test or access the page. Please Advise!

Thanks Greg
