It's a small problem, really, and sort of a first-world one by CM standards, given that it arises from some of my students actually doing their work at the beginning of a holiday weekend (on a really lovely day in the local area, where most of them are located, despite it being an online class), multiple days before the due date, but:
Why, oh why, when a student figures out how to solve a technical problem about which (s)he has emailed me before I get around to replying, doesn't (s)he email to say "never mind; I figured it out"?
