Hello,
I have made a terrible mistake by setting the username as incomplete bitcoin address. I have been mining 8 hours with wrong address. The wrong address had 2 letters missing from the end. Now I have fixed this error but what happens to the bitcoins I have already mined?
Wafflepool is not responding to my email, so maybe they can anwer here

He said he would be out of town until Thursday, so I'm guessing replies will be a touch delayed. Does the stats page pull data for the incorrect address you used?
