how to make grant access to user to post articles in wordpress?

Hi Steven,

Quick clarification question - Are your WordPress site and all of its posts going to be restricted to members? If so, you might want to consider using actual membership software to create the site, so you have the ultimate control.

Otherwise, I believe you are referring to assigning roles within WordPress. The codex has a section about what each role can do within your blog. The only part that isn't here is the registration part.

Roles and Capabilities « WordPress Codex

Here is a summary of roles from the Codex:
-- Super Admin - Someone with access to the blog network administration features controlling the entire network (See Create a Network).
-- Administrator - Somebody who has access to all the administration features
-- Editor - Somebody who can publish and manage posts and pages as well as manage other users' posts, etc.
-- Author - Somebody who can publish and manage their own posts
-- Contributor - Somebody who can write and manage their posts but not publish them
-- Subscriber - Somebody who can only manage their profile

In Settings > General, you can set whether each new member (subscriber) has to register, and whether anyone can register to be a member. Then you set the new default user role to Author, so the new members can post and edit their own posts after they log in.

See if that works!

The WP Role Manager Plugin might help you with this.
