Palm Muting Lesson

I was wondering about muting notes. Some of the songs I am now trying to learn feature mutes, and I just can't get them right. What exactly is a muted note, and what is the best method to do this?
It just so happens that I included a segment on palm-muting in the tenth beginner guitar lesson on About.com. It includes mp3s of what palm mutes sound like, and a description of how to play them yourself.
