This week, a friend of mine sent me one of those chain letters, we've all recieved once or more. Sometimes from friends, but more often from people we've never heard of: Chain letters that tell you to send a specific amount of money to the first person on the list, add your name to the bottom, removing the first person and then sending on the email to as many people as humanly possible.
I wrote an article and a short program that calculates your returns under different scenarios. How many people actually forward the chain letter? How many people do they send it to? You can find the article here.
