So if the guy that butted in was a flamer... it's okay for a mod to flame back? That sounds quite immature to me, and not very mod-like.
Of course, I don't see anything wrong with it, as I don't plan on becoming a regular in these forums... but it still struck me as odd.
And if 'flaming mods' are an accepted community standard, so be it. I would just hate to see him as a mod on the forums I go to...
