Change Author Name That Is Displayed
If you do not wish to use your real name on your blog posts, you can easily create a “pen name” or “nickname” to be displayed instead.
You can create a “pen name” or “nickname” by going to your user profile in your blog dashboard.
Select Users > Your Profile in the left menu.
From there you can change your nickname and display name to be something that will be displayed publicly. (Don’t forget to save your changes!)
