I'm Traveling in Europe, and My Wallet was Stolen

You get an email from a friend who claims he is traveling in Europe, his wallet and passport were stolen, and he needs a few hundred dollars to pay the hotel so he can leave.  Good news - your friend is just fine, and likely at home.  The bad news is that his email has been hacked into, and the scammer is sending out these emails to all of his friends hoping one of them bites and wires him money.  Don't fall for it!  Never wire money to anyone!  Never buy gift cards and mail them, and never agree to meet someone to deliver money.
