The yoville buck

We still have hurd many different things about the yoville buck . I've hurd that they might be used to play games at the yoville carnival ? I've hurd you can earn them for getting people to join yoville . But none of us are sure yet exactly what they will be used for . If you have know or have any idea's what they may be used for let us know . Every one is very currious to find out :)
