<p>This plugin is based around the concept of lists. You can create a list, then assign posts to it. (A post can only be on one list.) When a list is created, you edit the blog posts and assign them to the list. When a blog post is assigned to a list, they can be listed in your blog posts.</p>
<p>This plugin differs from the other ones out there, because it does no magic! (And that’s a good thing). You have to create a list. Assign various blog posts to that list.</p>
<p>You have complete control of your related posts, making this plugin a great asset when you create a series of blog posts, with different parts or chapters.</p>
