papergod's game archive suggests he was on vacation from 17 May to 24 May since those were the last two games completed.
For the future you might want to avoid any tournament with the setting "one game per opponent starts immediately". You are now in the worst case scenario where all other games were completed before the last one starts.
As well avoid tournaments where there is no "Max Avg Time/Move" restriction.
Edit: "Last move without moving" is normal for the start of a game.
But still, a game starts to count as soon as it starts; conclusion shoud be then, he left 5 hours later or returned 5 hours before I checked the game (or something in between). Right? So the phrase 'last move' is somewhat confusing since no move has been done.
Something very annoying happening at a tournament I am playing. One game is holding up the tournament. Strange thing is, it started 8 days ago but as I look at it, it says last move 5 hours ago but no piece has been touched??? How is this possible? http://www.chess.com/echess/game.html?id=20414166
