<p>Most of the “related posts” plugins out there while they provide some kind of control on how to create related posts, they all rely on an algorithm<br />
and the results are automatic. With CPTR you get total control as you can manually select the posts that you want to relate.</p>


Custom Post Types Relationships (CPTR)

This plugin will let you create custom post relationships among posts, pages and custom post types.
