If you actually know me, you probably either (1) already know my email address, or (2) are my "friend" on Facebook, in which case you can send me a Facebook message.
If you know someone who actually knows me, they can probably tell you how to reach me.
If you're reasonably clever and willing to work a little, you can find me on Facebook and send me a message that way.
If none of the above apply, I probably don't want to be bothered.
