This plugin allows you to create many-to-many relationships between posts of any type: post, page, custom etc. A few example use cases:
<ul>
<li>manually curated lists of related posts</li>
<li>post series</li>
<li>products connected to retailers</li>
<li>etc.</li>
</ul>
Additionally, you can create many-to-many relationships between posts and users. So, you could also implement:
<ul>
<li>favorite posts of users</li>
<li>multiple authors per post</li>
<li>etc.</li>
</ul>

It works great. The options are beautiful, thought for every need, for example change a label or show only "to" box.

Works great

I'm working with WordPress, after some updates or actions the plugin starts to work incorrectly. The code is completely unreadable and can not be changed, the author abandoned his creation.
You can use - https://wordpress.org/plugins/npc-neatekpostconnect/

Huge load, unreadable code, Alternative for that plugin

Efficient many-to-many connections between posts, pages, custom post types, users.
