Access permissions can be applied to any site visitor and site member.
There are two modes of operation:
General subscription
Subscription by user type
Each mode takes unauthorized people (site visitors or guests) into account.
You can limit the number of profiles that guests will be able to see, or you can prohibit the action entirely as well.
General subscription
As for the authorized users, you can go for the General subscription where everyone is supposed to upgrade their membership in order to be allowed access to this or that site section. It can be one-on-one IM chat, mailbox, LikeMe game, or a list of potential best matches, and so on.
Subscription by user type
You could go for the gender-based mode and distinguish between permissions for men and women or any other user types that you create.
Membership groups
You can create as many membership groups as you wish, decide on which activities to allow, then create activity periods for them and set prices.
For example, 30 days access could cost $7 for Silver group and $15 for Premium group, and so on.
This is what the list of membership groups will look like in the user mode:
