[Solved] 2 Teachers sharing class, how to have 2 accounts as the teacher?

I work part-time and my teaching partner works part time sharing a class. How do we attach 2 teacher accounts to the same class so that when a student asks a question, the teacher answering it is able to from own account? Otherwise 2 teachers are sharing the login information, and only 1 teachers name shows up. It looks like 1 teacher does all the work, and the other does nothing! Aside from renaming it to Teaher, how can I do this?
