I'm trying to add a librarian to my course, and it was suggested that I add her as a Course Admin. However, I had already tried adding her as a TA (there is no Librarian role). I can't find an answer on how to change a user role once they've been added - and I don't see the option on the People page.
I tried deleting her enrollment on my course site and re-adding her with a new role, but it automatically showed up as TA role again.
Thanks in advance!
