I want to be able to give access to a user to modified and manage all user except the administrators (me). I looked for plugins and hooks I couldn't fine anything. The only solution that I can think of is to modify the admin/users.php file but the I am not going to be able to update wordpress or using the "init" hook stop wordpress from rendering the users and recreate the users.php file. I just want to know if there is a easier way. Can add a hook be added in the users,php file in the next version to modify the '$wp_user_search' object.
