what: telling should be possible to invis players
why: it is possible to use channels for communication anyway (all of them
party/ss/public) - so why is direct communication not possible ? I'll give an
example where this is useful: I am invis (and newbie) and standing before a
big monsie. As soon as I become visible I will be only few seconds away from
death. It would be convenient to be able to negotiate a summon a way from the
monsie (preferably without spamming channels).
