On a moderated bboard, it might be nice to be able to edit posts
before approving them. That's what Yahoogroups do. However,
once the postings are made, then they are there for eternity.
Another argument against allowing someone to edit bboard
postings is the fact that there are email alerts on the postings.
Will you send out corrected postings? Or would you make the
corrected posting "stealthy"?
