Bernard, I often do that with serious matters. I have had conflicts where I sit down and type a 2 page or more letter thrashing something on someone then do not even send it. I may have wasted a hour or two but I got it out, even if only to myself. That is why journals are important.
I have vacillated on the Guest posting issue. I have concluded that some intelligent, good folks need anonymity to post. Some of the posts are excellent, thought provoking, and raise the level of the discussion. Therefore, let people continue to be "ghost writers" as long as there are no salacious attacks as happen recently when the whole thread was deleted, then partially revived.
Let the mudcat elves remove the "mud" slinging posts even if continuity is somewhat broken.
Ol' Dave likely just needed a break from the vicissitudes of this section of the deep, sometimes murky, muddy section of Mudcatsville. Catfish are bottom feeders and some of the Cats here a bout's are as low you can go.
