This example jekyll site has 4 authors: John Doe, Jane Doe, test1, test2.
John Doe has 6 posts.
Jane Doe has 10 posts.
test1 has 0 posts.
test2 has 0 posts.
The pagination setting in _config.yml is set to 5 posts per page. Hence, the author pages show their respective posts and when the number exceeds the per page limit, a pagination trail is shown for navigation.
This is done using the jekyll-auto-authors plugin. Please read the setup article to learn more.
