I'd just poked my head in to the CMB before closing out the Round 1 thread for a RPG board game and saw like half a dozen differently named posts, when I got done and came back to read to see what was up several were missing. Hindsight of course the titles were pretty obviously edited and named as deletion requests... haven't had too much problem myself with double posts but we actually had a few in the game thread recently and they seem a bit more common of late, or maybe I'm just noticing them more.
