Add the ability to ask questions about a request

This is a harder item than some of the other tickets I've created; it's more of a wishlist thing.

It might be nice if instead of rejecting or accepting a request, admins could ask, "huh"? For example, consider a request that just says "trying to log in" Is that a real request? Did the user not understand what the instructions said? Or is it just automated spam?

If we had a feature like this, it would probably need to go along with a feature for users to edit their requests or cancel them.
