To add a new user to your site navigate to “Users” in the left-hand sidebar and click “Add New”.  First enter a username and an email address in the first two required boxes.  In the following boxes you can add a first name, a last name, and a website URL to associate with the user.  Next you must enter and reenter a password.  A Strength Indicator is provided to help guide you in making a strong password.  You can choose to forward the new password to the provided email address by checking this box.  Otherwise the account will be created without a password notification sent.  The final option is for selecting the role of the new user.

There are varying rolls built into WordPress that allow different levels of access on the site.  “Subscriber” is the default setting, and it is for the basic user that can login and read content.  They cannot post anything to the site itself aside from comments.  “Contributors” are the next level up.  They are granted access to the “Post Editor” and can submit content to the site blog for review.  Contributors cannot by default publish their own content or upload any media files to the site.  “Authors” can do everything a Contributor can do, but they’re given the freedom to publish their own content and upload media to their own posts.  They have the ability to add content without anyone checking it, and they can edit their own content after it has been published.  They cannot, however, edit or modify any content that they did not create.  “Editors” can do everything that Authors can do, but they are also given the ability to make modifications to content made by other users on the site.  This allows them to correct errors or remove content altogether when other users create them.  “Administrators” have complete control over everything on the site such as themes, installing plugins, and user account creation and editing.  When you are satisfied with these settings click “Add New User” and your user will be added to the database.

To edit a user navigate to the “User” button in the sidebar and select “All Users”.  You can modify a user by hovering over a user and selecting “Edit”.  The “Edit Profile” screen gives even more options then when the user is first created.  You can assign a “Nickname” for your user and assign how their name is publicly viewed on the front end of the site.  When everything is as you want it, remember to select “Update User” to save your settings.
