With a scam like this, the goal is usually to send you a cheque, but it's for more than is required. So then they ask you to deposit it and withdraw the difference to send back to them. By the time you discover that the cheque has bounced, they have already got your money and they are gone. Unfortunately, there is not a whole lot police can do about these types of scams because it is so hard to trace to the criminals. They are usually overseas in places like Nigeria and use cyber cafes to send out their scams. If anyone wants to read a really great book about this whole thing, read "419". It is fiction, but is based on the reality of internet scammers in Nigeria. It is fascinating and gripping from start to finish. I doubt anybody needs to panic about giving your address at this point, but if you do receive a cheque, take it to the police and under no circumstances should you cash it!!!
