Another difference between & im; and email is that with & im; you can see your friends ' presence, that is, whether they are actually on-line at the same time as you. This lets you send messages truly instantly, instead of sending off a mail and having to wait for your friend to check their mailbox. An & im; message pops up on the other person 's screen as soon as you send it. Of course, if you 'd rather not be interrupted, you can change your own presence so others will know not to disturb you
