Show list of available memberships to new user

Hi Folks,

Question: how can I show the new, non logged-in user which memberships I offer? When I setup Membership 2 I have the page "Membership List". But if I click on this link I need to register befor I can see, what memberships I have. This makes no sense. I want the user to see all available memberships, than to choose one of them and go on with the login.
I have another weird problem. I have 4 memberships available (two more but they are disabled). After my registration only one membership is shown. And this one is one of the memberships that are disabled in the backend. What have I done wrong???
