X3P0: Authors is a block that lets you display a simple list of post authors for your site. This is especially useful if you’re coming over from using a classic WordPress theme and need a block that’s similar to the old <code>wp_list_authors()</code> template tag.
Aside from the full array of normal block design tools, the block lets you choose from several options:
<ul>
<li>Number: Decide the number of authors to list.</li>
<li>Order By: Choose from a variety of fields to order the list by.</li>
<li>Order: Whether to display the list in ascending or descending order.</li>
<li>Has Published Posts: Whether to only show authors who have published posts.</li>
<li>Show Feed Link: Whether to show an icon linked to the author’s RSS feed.</li>
<li>Show Post Count: Whether to display the author’s published post count.</li>
</ul>
