I've never seen a moderated newsgroup that was worth a damn.
Even WikiPedia.ORG allows flame wars ( on the talk pages ).
Better systems have yet to be developed, I imagine.
Near as I can tell ( after a quick look ),
Big-8.ORG ( whoever they are ) are in charge of
Sci.Physics.Research ( including it's creation ).
They approved Sci.Physics.Research's Editor-In-Chief
who ( in turn ) approved the moderators.
I don't know ( nor care to find out )
what Sci.Physics.Research's agenda might be.
