I want to give TA permission to share folders and mailing lists for classes
You will need to add the account to the lesson group with the same talent as granting the rights of the LMS and shared folder of Scomb to the TA, and adding to the lesson ML.
Please refer to the "2.4.2 Add user to group" in the URL below.
