Sprite Yard is a social networking site designed to be used from your cell phone. To join Sprite Yard you have to first buy a bottle of Sprite. Then you use the code under the bottle cap to get to the sign up page for Sprite Yard. I'm sure the URL is also on the bottle.

Once you're in, you need to keep buying Sprite. Under the bottle caps you'll also find codes for ringtones, free downloads of Sprite content called visitones and mobisodes. So, drink up and have fun!
