It was a thread on who'd piss of a crowd of people fastest - Red Dawn or Russ.  Both participated in the thread good-naturedly.  At the end, a mod locked it and posted a line in Red's post, without a signature.  I think it was taken as evidence that Red's a mod.  ???  I forget exactly what the mod-quote was.  Nothing that I thought was particularly indicative of his modness.  But, I have my other sources as reason to suspect Red, though I don't think he's a mod.  *cough*swforums.com *cough*
