I just checked my account and it looks like my payout address has been changed and locked (it's now 6xEjXTc9cSJzDatsBD63Z1WnT8GjLKP8au which is not mine).  My payout address should be: 6xuUB9KPQN8uDRZ5kuAaHjCNy4RyPu6pTK

I can't work out how to contact Digger, the site admin, because there is no email address for him and I can't send private messages on the board yet.  If anyone can assist then that would be great.

It's a little disappointing.  I think I had just got enough coins for the payout to work and then this happened.
