This should apply to all forums.
Also, can we lay out some guidelines for succinctness/conciseness?
IMO, to the first point above, if you let the 'adult' fora use abusive and vicious language (in relation to anybody, team, player, whatever) and yet state that such should not apply for the 'junior' fora, you're asking the impossible of the latter. The lowest common denominator will seep over and outwards. That's how it always works, like it or not.
I copped some reverse heat yesterday, but I really admire what GAGR has tried to do for the sport and I am convinced that if you don't adopt and reasonably enforce the overall standards you note above, you will find that many of the 'adult' fora decline to be little more than the sandpits of 20-30 consistent hardcore posters that don't mind - in fact actively like - spitting it out rough. A lot of people don't enjoy communicating that way, and the notion that 'oh, this is a rugby forum, so cop that sweet mate' is not good enough with the overall, long-term interests of the game in mind.
You do such a really good job here on thin resources - why not aim to have 900 people logged into the 'adult' fora, not the typical 30-50 I see most days. I mean, 40,000 + go to Test matches. I would like to see more people by far start their (rugby) day with GAGR than Rugbyheaven, and btw I think you could achieve that.
