Chatnap is the Instant Messenger chat game where you challenge friends who have left their instant messenger on but are gone!
You use Chatnap to create a URL that you paste into a friend’s instant messenger window. If the friend clicks the URL within five minutes they win a point and you lose a point. If they do not click within five minutes then they have been caught chat napping and they lose a point and you win a point.
Sign in under START then under CHALLENGE you can create a friends list and challenge your friends. Under SCORE you can see your score and your friends’ scores. Even sign up for an RSS feed to keep track of whenever they score or lose a point.
