USay is a nice script to add to MSN Messenger that lets you steal the nickname of the person you're chatting, ie what you seem to write what he is writing it out with your nickname. Which leads to confusion and a lot of fun especially if more than two people added to that conversation. Even Usay can mimic the style of the font you're using the other person (only from version 1.1), and the letters are identical and you will go through it much more convincingly. This script only works on installing Windows Live Messenger or Messenger Plus Live.
