You are lucky too.  You just joined and already you won today's draw.
( I use random.org, in case anyone is interested, to get a true random number every day and today it gave me #36, the last number added to the draw list. )

But 2 or 3 of the sites said that your address has already been used today and so didn't pay out.  You should use another address when you are checking these sites yourself.
