Import Existing Authors
The first time you use the app, you have the option to either "Add New Author" or to "Import Existing Authors".
To import existing authors, click the "Import Existing Authors" button.
This will scan through all the authors that you have used in your blog articles previously, and display them.
Select the authors you'd like to import and hit the Import button.
This will then import the authors, which you can then Edit to add a bio and/or image (for Pro plans only).
