I don't know if this had been discussed here or not. I browsed and searched but did not see anything come up
It would be great that in the process of approving entries, that a teacher could supply feedback to a student about an entry and ask them to tighten up/fix/change the definition. The options now are to, approve, delete OR the teacher can edit. From the pedagogical point of view it would be great for a teacher to guide the student to the correct definition of the concept instead of just outright rejecting it or editing it his or herself.
