A famous chain letter is the “Little Kimberly Anne” available from http://www.eff.org/Net_culture/Folklore/Chain_letters/sick_girl.letter
Look at the letter and answer the following questions:
1.What did she want to do, why?
2.If you send this letter out to 20 friends and each of them send to another 20 friends, how many emails will be moving around after just 4 rounds?
