Membership

Hello,

I would like to make my new site with membership. Thats why i bought your plugin. I install it and now i have to configure it and i need some help.

Ok, my site will have 3 levels membership.

1. Free content
2. Access to old stuff from previous members who paid for these stuff . They are not going to pay anything
3.Paid members, who will have to pay an amount to have access for contents but it is not per month it is just for 12 posts and then they have to pay again for the next 12 posts.

Any idea how i can do that?

Also something else, where can i found the register form for my site? is it available any plugin to register and login features ?

Thank you for your time
