I scanned the list from back to front and checked those with posts over 500 figuring, "Actively Posting" would easily put you over that mark. I also checked a lot of "Last Posted" date in their Profile's to see when was the last time they had posted. Not scientific, and I used my judgement (good or bad) as the case may be.
Too humble to not be corrected. Sorry Ba-Dg-Er and others!
