"Robots or "BOTs", are software programs that you can add to MSN® Messenger and Windows Live™ Messenger. If you add a robot to your contact list, it can chat, give you customer service support, perform searches, make suggestions, play games and more.
We’re looking for the best new robot ideas for Messenger. And $40,000 in fantastic prizes go to the top BOTs!"
