USay is a fun script to add to MSN Messenger
that lets you usurp the nick of the person you`re chatting with. In other words it looks like what you are writing is what they are writing because you have their nick. This can produce confusion and fun, especially when more than two people are talking.
USay can even imitate the font style the other person is using (only from version 1.1 and later), and so the letters will be identical and you can pretend to be them quite convincingly.
This script will only work with Windows Live Messenger
or Messenger Plus Live
