I've just received a WWmail from 'madamkeita' - it's a standard scam letter; a sob story promising big rewards if I provide her with a bank account to use, etc. If she's putting this out to everyone, then make sure you don't respond.
Becca started a thread on Lounge Forum 'scams are becoming more inventive', that has more background to this kind of thing. If you want to know more, just go to:
