I found it via this article about LifeLock which was linked to by Bruce Schneier, my favorite security guru.
Hopefully over the next few months it will cut down on the amount of junkmail I get. I am also considering calling the credit company and putting a fraud alert on my account. Unfortunately it expires every 90 days so I would have to call them every 3 months to keep it going which would be a pain. That is all Lifelock does for you. The credit bureaus really should be taking these precautions anyway. But it costs them extra money to have to actually verify requests for credit so they try to avoid it.
