Unregistered (Guest) Authors for post types
Guest Author plugin allow you to add authors to posts without registering them as users.
Sometimes we have blogs of different authors, but we are not interested to register them as wordpress users. In this case usually we will create some custom fields and add those details.
With this plugin we are implementing a common way to do that.
Here we listing all authors together at one place using a custom post type. We can add full details of those authors, like bio, social media links, job details, contact details and photo.
Then we need to check where we want to(custom post types, pages) display those authors, then we can select those authors from each post type easily.
