Word of caution: prohibition of anonymous posts seems logical and sounds like a good idea, but:
a) It can never really be enforced - people can always find a way to defeat it if they want to bad enough; and
b) attempting such has lead to the ruin of many good discussion groups prior to this one.
Dan King can attest to all of this, as can Tommy N. or any of us who found rec.sports.golf, golfonline's grill room and equipment forums, as well as several others, beginning quite a few years ago.
My advice, unsolicited, take it for what it's worth, is that ignoring inflammatory posts, plus a lot of HOPE and good faith, is the only way to keep a DG alive and healthy.
I have high hopes for GCA. But that being said, if a few ill-meaning individuals want to ruin it, they surely could. Thus I am always wary of GCA getting too much press... sorry Ran!
