determining that a change, which was not inspired by the instant messaging identity, in the membership of the passively dynamic group of instant messaging participants has occurred; and
automatically triggering, without involvement from the instant messaging identity, an updating of the displayed instant messaging participant list to reflect the change in the membership of the passively dynamic group of instant messaging participants.
2 . The method of claim 1 wherein:
determining that a change in the membership of the passively dynamic group of instant messaging participants has occurred includes determining that a new member has been added to the passively dynamic group of instant messaging participants; and
