When emailing, please add the word "hn" to the subject; otherwise, your email will likely become lost in the sea of spam that account receives. Thanks.
Addendum: I've responded to several email requests that have produced zero follow-up. The occasional occurrence I readily accepted, but I'm to the point of saying, don't email me unless you're serious, or at least respectful.
