Lol, I'm not sure if "loud" isn't a little too specific.

However, the drop down list of categories is a good one. I'd intended something like that. I'm still debating a hierarchy or flat category list. The database design currently supports the hierarchy model, but they're difficult to implement well and have a number of sneaky pitfalls.

I do think letting the instructors have as much involvement as possible in data entry is ideal, as it offloads admin work and hopefully increases accuracy.
