     Not if you permit the use of retroactive moderation as an
alternative to preapproval moderation.

     Retroactive moderation is moderation through the removal of
inappropriate articles *after* they have been posted.  The current
model is the "tit-for-two-tats" version in which the first off-charter
article from a given poster draws an admonishment (and a copy of the
newsgroup charter) and any subsequent off-charter posts are rejected
(by a cancel or supersedes message).  The mechanism by which retroactive
moderation achieves an improved signal/noise ration is by discouraging
authors from posting off-charter articles in the first place.

     I would like to suggest that the option of retroactive moderation
also be offered as a "middle ground" between "central control"
moderation and a completely open group.

     Numbers 2, 3, and 4 are addressed somewhat differently by
retroactive moderation.  The moderators duties' are little more
difficult than reading the group and admonishing or removing the
occasional off-charter posting (functions which can be done from
within trn with the help of the proof-of-concept scripts.)  If someone
has time to read the group, they have time to moderate it.  And,
moderation can be distributed among any number of moderators... the
retromod control messages use message-id conventions similar to those
used in spam cancels to prevent more than one admonishment or
rejection from acting at any particular site.  Thus it is volunteers
from among the readers and posters in the newsgroup community who set
the standards for how that newsgroup will interpret its charter.

    Yes, but this is not a problem for a retroactively moderated
group because it remains marked "y" in active file... people may post
directly to the group rather than through a moderator or

     Yes, the "central control" registration and moderation procedure
would require considerable administrative effort... this is another
advantage of retroactive moderation - it is a distributed effort with no
need for registration or even a single "choke-point" for posting.  It
will be as robust as, but less noisy than, an unmoderated group.
Retroactive moderation is also suitable for groups that are gated to
mailing lists.  The admonishment and rejection messages should be
filtered out of the mailing list stream.  Those who get the mailing list
will derive their benefits from the decreased rate of off-charter
posting that retroactive moderation will gradually achieve.
