Used to thought this function was banned. never went to that direction. nice touch!

@Bainhome, Cody banned the reverse of this function because it could be used as a cheat to unfairly reduce Cody score. I do believe the function used cannot be in such manner...so it is not banned and free for your use. Enjoy!. :)

@Bainhome, Cody banned the reverse of this function because it could be used as a cheat to unfairly reduce Cody score. I do believe the other function cannot be used for such purpose...so it is not banned and free for your use. Enjoy!. :)
