restricted user read different posts

Here’s a summary of the “roles” available within WordPress as described in the WordPress Codex Roles and Capabilties:

* Administrator – Somebody who has access to all the administration features
* Editor – Somebody who can publish posts, manage posts as well as manage other people’s posts, etc.
* Author – Somebody who can publish and manage their own posts
* Contributor – Somebody who can write and manage their posts but not publish posts
* Subscriber – Somebody who can read comments/comment/receive news letters, etc.

So by default, I don’t believe the roles restrict access to the blog but rather limit a users capabilities within the blogs administration (i.e. – a subscriber can only read the blog but an author can write to the blog, etc).

Again the Roles and Capabilities Codex goes into further detail. Plus there are a number plugins available that expand this function of WordPress. Here are a list of plugins created by a WordPress user that creates blog restrictions.
