Capability Manager is awesome for managing back office user admin but can it used to allow different users different access to posts/pages
e.g all Posts/Pages are marked with a security level between 1 - 10. Every user has a security level between 1 - 10. Users who have Security level 5 will not be able to see posts level 5 or above.
Users who are not logged in will only see posts at Level 0.
