I suspect people may have missed the point of my earlier mail :-).
We now have some seven or so dispute resolution channels. That's probably more than the number of editors willing to get stuck in and mediate at any one time. We're spreading a very small resource ever more thinly.
We need, rather, more people getting involved. If more people responded to RfCs in a constructive, mediative manner, we'd probably see fewer cases going to 'official' mediation and even the Arbcom.
