Free service to contact others in case of emergencies and get police reports

Passed this on from a friend from the OEM:

I just registered for a great new service. It's called Nixle (www.nixle.com) and you should register too. It immediately connects you to trusted, important information by text message, email, and over the web. By registering, you not only get your police department alerts and advisories, but you get to send messages to your neighbors and connect with any community groups that you are involved with, it's amazing. You can easily sign up by going to www.nixle.com. Make sure after you register to tell your friends and neighbors to sign up too. It's the neatest new thing.

P.S.- It's not available everywhere yet, but you can register for as many addresses throughout the country as you like. That way, you'll stay connected to everyone that's important to you. And as each location becomes available, you will immediately begin receiving the information.
