How to Manage Users and Authors on Your WordPress Blog
The WordPress Users page tells you about all the users on your blog. It lists each user’s username, name, e-mail address, role on your blog, and number of posts made to your blog.
To manage user roles, you need to understand the type of access each role provides:
Follower: This default role is assigned to anyone not logged in or anyone who leaves a comment. Followers receive e-mail updates whenever you update your blog with new content, but they don’t have any editing privileges.
Contributor: A contributor can upload files and write/edit/manage her own posts. When a contributor writes a post, however, that post is saved as a draft to await administrator approval; contributors can’t publish their posts. This feature is a nice way to moderate content written by new authors.
Administrator: An administrator has the authority to change any of the Administration options and settings in the WordPress blog. As the account owner, you are already listed as an administrator. You can also assign other users as administrators.
Editor: In addition to having the access and permissions of an author, an editor can moderate comments, manage categories, manage links, edit pages, and edit other authors’ posts. Editors can also read and edit private posts.
Author: In addition to having the access and permissions of a contributor, an author can publish his own posts without administrator approval. Authors can also delete their own posts.
WordPress lets you have an unlimited number of users and authors on one blog, which is a nice feature if running a multiauthor blog is something you’d like to do.
To change a user’s role, follow these steps:
Click the All Users link in the Users submenu.
Locate the name of the user that you’d like to edit.
Select the check box next to the username.
From the Change Role To drop-down menu at the top of the page, choose the role you want to assign; then click the Change button.
The Users page refreshes with the new role assignment applied.
To view all the posts made by an author, click the number that appears below the Posts column for that user.
