Very simple, but effective

Features are very simple: Create some groups using this plugin. Then create some users using the standard WordPress users manager. Then edit those users and assign them to the groups. Then create posts or pages, and assign them to the groups. Done.

There is a nice bunch of settings, quite mindful; go explore there before deciding this plugin is too simple for you. The [L] hint for administrator stroke me as a really nice idea, ultra simple to explain to my customer.

Thanks for the plugin. I’ve noted 5 stars because it does exactly what description promises.

Tested 1.2.5.0 on WordPress 3.9.1 and it works.
