It's an excellent idea. 

Not sure if parties intent on arguing will change just because we all post "take it to sitemail". But notifying the mods the moment we think it necessary to remind folks -- and by "we", I mean "you" (because you're a natural peacemaker, and I'm not) -- may really make a difference. In any case, some people will get the message. So it's worth doing.

Perhaps we could make some "Take it to sitemail!" banners to post. Make it fun! (I'm not kidding.)

Anyway, I have to admit the one quarrel I got into recently, I actually thought the other party was joking, right up until the last few posts. If I'd listened to your timely calls to stay on topic, it would never have got that far. :)
