Icon next to instructor name in Discussions (?)

Community Champion

This week we started a MOOC with 2,500+ participants and eight or so faculty facilitators.  I've noted instructor and TA replies in the Discussions do not stand out from the students and so it is challenging for participants to differentiate between the reply of a peer participant and that of an instructor.

This had me think back to how this was handled in our prior LMS and I recall an icon/badge appearing next to the instructor name for each discussion post.   I am curious if others in the community feel such an identifier is needed.   Would such an icon have value for the MOOC alone, or for any course?  Your thoughts?
