This service is a directory of people and groups at the University of Michigan. All current members of the U-M community have profiles in the MCommunity Directory. This includes faculty, staff, students, retirees, alumni, and sponsored affiliates. Anyone who has a profile in the directory can create groups in the directory. It is an an enterprise directory; it covers the entire university. It is part of a larger identity management system that allows the university to know who is and is not a member of the U-M community so that central offices—as well as departments, schools, colleges, and campuses—can grant and remove access to their online resources as needed and appropriate.
