When I was teaching through UCSC Extension, one of the students asked if I would meet her outside of class for intensive, one-on-one instruction in editing. I agreed. Turns out, she'd been recently hired as an editor by a major player in the industry, and she now found herself in over her head because, actually, she couldn't edit. Her background?
