Betsy, that's a riot! You'll have to update us if the scammers fall for it. I remember seeing a website once with people who play with scammers. It made for some really funny reading!
Sam's Mom, this type of email is a classic scam, probably originating in Nigeria, not Sweden at all. They offer to pay for something, usually of high value (i.e. horse, car) and will pay with a cashier's check. They tell you that they will pay you significantly more than you are asking and all you have to do is cash a very large check, then wire money back to them (there's always some reason why you need to do it this way). By the time the bank comes back and tells you the check was a forgery, you have wired the scammers your very real money. The emails that tell you you have won a foreign lottery are the same. The last one I got was a "woman" who started out calling me "dear one" and wanted to share her late uncle's very large estate with me. LOL
These have been around for ages. I thought everyone was onto these by now!
