Love this plugin!

This is a wonderful plugin and I’m so happy to have found it. It’s easy to use and works perfectly. Many similar plugins are complicated and annoying to use, but the BU folks have managed to pull off a nice user interface that makes sense. This plugin brings sanity to the content permissions space.

You also might want to check out their BU Versions plugin, which allows editing of content that is already published without it being immediately overwritten before a review.
