Been Plated allows you to communicate with people using only their license plate. Here's how it works. When you sign up for the site, you can follow as many license plates as you want. If any of your license plates receive a message, you will receive an email or text message letting you know that it has "been plated." You can also read any of the messages other members have posted, and even comment on these messages. In a way, it is as if everyone now has a "how's my driving" sticker on the back of their car.
Been Plated launched July 1st, and already has a loyal following. The site is compatible on all mobile devices, and already has an Android and iPhone app.
