WP User Groups

This plugin is tremendously solid. Used it to build a complex system of content teams who could only create or edit content within their own team. WP User Groups handled the "teams" of users which corresponded with taxonomy terms associated with the content. Works like a charm. Plugin itself is lightweight and simple to grasp.



Solid foundation for development

I've been using this for a fairly complex WP build and I've been very impressed. The back-end is easy for users and there's a nice API for devs. Two thumbs up.

Very well-executed

When you need to group your many users beyond just their role, this is the pluging. Works very well, properly coded.

Very useful
