How does a PI set a group admin?

A Principal Investigator (PI) may assign a user in his or her group the role of group administrator.  The group admin has privileges to carry out administrative functions for the group, such as adding new users, and giver group members access to HPC resources.  The group admin must have an MSI account within the PI's group, after which the PI can connect to myMSI and designate that person as group admin on the "Manage Who is Allowed to Administer my Groups" menu.
