I thought this was going to be a message from the most interesting department in the world: "We haven't received many signals, but when we do, they're in Latin" On a serious note, thanks. That's helpful. Have you (any demand side) received uninformative text with the signals you have gotten? The official "advice" (if there is any) is just to specify the position you are applying for.... We haven't received many signals over the years (small school) but the ones we have have often seemed out of the blue. Some explanation might be helpful, in particular if its a good one.
