I have had a few letters published, and I have received anonymous mail from people who called me names, and phone calls from strangers, but since I live in a small town, my name is easily recognizable.
I have accepted that such behavior is part of the price we pay for putting our identity out in the open, but adding phone numbers makes it too easy to call the writer on the spur of the moment, looking the number up may be enough to deter some people.
And please, DON'T publish my email address, I get enough spam as it is, publishing it will put it out there for spambots to mine, as well as making it too easy for nasty letters to be sent.
Name and town are enough, any more information in too much information.
