Not final yet, but the draw will look like this for the 1st round:
No player will play the same opponent more than once (barring substitutions or me seriously screwing up)
Side selection wil be random, but no player will play the same side more than once (barring substitutions or me seriously screwing up)
Players with a preference for Vassal will be grouped with each other, and with potential opponents chosen from the players who did not express a preference for Cyberboard
At the moment it looks likely that there will be only one Vassal game in each round
Then the players who expressed a preference for no move files will be grouped together.
The remainder (really the bulk of the players) will then be randomly drawn together.
Family members (at the moment I think Mulls and Days) will not be drawn against each other in the initial rounds
No more than 2 refs will be drawn agains each other, no Refs will play against each other in Round 3
