Sounds like it might be a cookie issue. First suggestion is to log out and log back in again.
FYI, I'll PM the CM so he knows about this ASAP.
As to the Notary thing ... do they have Yellow Pages in the UK? If so try looking in there, you'll probably find more of them than you can shake a stick at. Back in Canada there were more listings for Notaries then there were for garages and used cars.
As to the bank stamp thing I couldn't say, but ask the casino people. They'll know what they're willing to accept.
