From the project page: "This module allows fine-grained access control of user administrators, by providing various editing protection for users. The protections can be specific to a user, or applied to all users in a role." I'm giving up all of my contrib modules to focus on co-maintaining the Project* suite. I'll only be maintaining this module for another 30-60 days, so please contact me if you're interested in adopting it. Otherwise it will be abandoned and unmaintained. hunmonk
