Looking for a way to allow instructors to provide personalized feedback effectively and efficiently, while maintaining the flow and momentum of a particular discussion with a student or class.

Adapted from Elise Springer's comment on http://moodle.org/mod/forum/discuss.php?d=32698

a vehicle for confidential evaluative feedback.

Emails/IMs don't work well when graders (TAs) as well as professors need easy recognition (as professor) of whether a TA has shared feedback with a given student. Having the confidential comment in the forum thread, but visible only to the individual student, professor, TAs, specific roles, would be ideal.
