It used to be vCash and then changed it's name to credits which you could use to bet virtually on matches. Since Larry Scott and his mob at the WTA were filing a law suit against WTAWorld (also not that this site was called WTAWorld.com a few months ago but name had to change because the real WTA Tour didn't want anything to do with this site even though it is the largest womens tennis board on the net) because they considered betting virtual credits as an act of gambling which brings up big hoo haa topic in tennis, so the site owners had to quit the virtual betting on matches to please the WTA.
It's worthless now, you can't use it for anything really. You can increase it by posting, making threads and taking polls.[/rantoverandpleasebringbackvbookies]
