Could someone with the merest scrap of WordPress sense take a few moments to explain to me, either in comments or via email, how to password protect a post?  I have some thoughts I really would like to get out, and perhaps publicly publish at some point, but they are refusing to even consider coming out to play without a little more privacy.

Or perhaps they are just pouting, waiting for a pretty lock, like the ones The Curious Nomad collects, at flickr and etsy.
