In addition to your own self, you can invite others or let total strangers on your WordPress blog register as a new user to post their own content i.e. articles, blog posts, etc. Here’s how you can do it;
First of all, enable User Registration in WordPress Dashboard –> Settings –> General and checkmark “Anyone can register” next to Membership.
Next, select the “New User Default Role” from drop-down menu labeled as Subscriber, Contributor, Author, Editor and Administrator.
Finally, you can advertise a link on your blog for users to easily register as a new user i.e.
https://website.com/wp-login.php
or
Whenever a new user visits the above website link, they will see this Login screen. Here they can click “Register” link and enter their new username and E-mail address. Next, they’d need to open their E-mail inbox to click the Confirmation link. That will successfully register them and they’d be able to login to the blog website;
WordPress User Roles
Super Admin – somebody with access to the site network administration features and all other features.
Administrator (slug: ‘administrator’) – somebody who has access to all the administration features within a single site. (WARNING: Do NOT allow this type of registration as a new user since they’d be able to take control of your whole blog website. Instead, you can manually create their users via your own super admin dashboard).
Editor (slug: ‘editor’) – somebody who can publish and manage posts including the posts of other users.
Author (slug: ‘author’) – somebody who can publish and manage their own posts.
Contributor (slug: ‘contributor’) – somebody who can write and manage their own posts but cannot publish them.
Subscriber (slug: ‘subscriber’) – somebody who can only manage their profile.
