Q2.2 What are some possible problems for moderated groups?

    Since messages are sent to a single moderation address, anything
    relying on that address is a possible single point of failure for
    the moderation process.  However, most types of system failure are
    shortlived, and operation of the group can resume rapidly.

    Another possible problem is that the moderator will "burn out"
    - get exhausted from dealing with the volume of messages, questions,
    complaints, arguments, etc., etc.  Having multiple moderators or
    being able to hand off the responsibility to a substitute can help.

    If the people posting to the newsgroup and relying on the moderator
    remember to be reasonable and courteous that can help a lot as well.
