    The stability of the MOO should not be affected, altho 1000s of users
    might preset a problem with the load of the machine it works on, and the
    lag inside the MOO. LagdaMOO for example, lags with a mere 150+ users.

    Also keep in mind the MOO is a single process, if you plan to do a lot of
    'heavy' tasks inside the MOO, you will lag even more -- you cannot devide
    the process over several CPUs, it will use only one. Also make sure the
    machine you run it on has enough memory, and set the max connections up a
    shitload, the standard is 64, which limits your userscount to 56 i think.
    You have to change this inside the MOO too.

    Lastly, you will probably have to edit the say, emote and tell_contents
    (if you will use the LambdaCore) of the MOO, because you will most likely
    get a "Task ran out of ticks" error when using them in a room with 1000+
    players, not to mention the InCrEdiBle SPaM it would create :-P

    If you only want a chat room, I would seriously advise something else
    different thn a MOO. There are MUSHs, MUCKs, MUSEs, MUDs etc, out there,
    which do just about the same if you only want to chat, and are less
    systemintensive (in particular concerning memory). Heck, you can just as
    easily set up an private IRC channel like thing, which would have nothing
    but chat, and would be much, much less demanding. It really depends on
    what you want to do :-)

    Greets,
    Thomas.
