Simple but efficient

I was looking for a simple plug-in to restrict the visibility of posts/pages to only certain categories of users.

This free plug-in does that perfectly and it is easy to set up.

The only drawback – and explains the 4-star rating – is that there is no bulk mechanism to assign existing users to one of the category created with UAM. This has to be done manually which may be a real drawback if you have hundred of existing users (less than 100 in my case)
