A lot of people have elaborate "contact us" forms you have to fill out and submit and then no one ever returns your correspondence. That's silly. Just email me at firstname.lastname@example.org and I'll write you back. It may take a few days if I'm on the road or teaching a camp or something, but I will write back. If I don't write back, try again at email@example.com because maybe your email went to my spam filter and that would make me sad.
