I can change my Display Name in Querki

(User Story, Closed -> Fixed, Priority: High, Test Status: No automated tests yet , Reported By Bad Link: Thing 3y284oe not found, )
Summary: There currently is no way to change one's Display Name; there totally should be. (Changing handles is not necessarily allowed, and has a lot of consequences; changing Display Name should be safe.)
IMPORTANT: remember the duplicate data between Identity and Person -- Display Name exists in each. Do we need to auto-update the Person record the next time you log into that Space, or something like that?
