In the electrical engineering classes that use Webwork, we often encounter questions via the "email the instructor" button that cannot be resolved by simply looking at the students' answers. The instructors or TAs ask the students to email them scanned copies of their work, e.g., how they got the equations for a circuit. It would be most helpful if the attachment could be made via the "email the instructor" button's email window. This would allow multiple people to look at the work, multiple TAs and instructors. the most available one could respond to the student quickly.
I think I'[ve seen this request before, but I couldn't find it with a search of the Forum. I fear it is not an easy fix, but I'd like to put it on the table for consideration.
