If it's not possible to have everyone play against everyone else, I think the tournament results won't be entirely accurate, because some will get lucky with their opponents, and others won't! Let the tournament last for at least six months! The last tournaments lasted about the same amount of time anyway. But, of course, we need to come up with an effective control system to prevent people from stalling. I suggest the following: at the end of each month, each player should have played at least 3 games. If they play fewer, they should be penalized 0.5 points for each unplayed game (2 points is a lot, considering the proposed scoring system). If a player warns in advance on the forum about their temporary absence, they shouldn't be penalized!
