so you can email people suggesting they start game 3.
with any issues being resolved by the players (if anyone can't play... the rules stipulate : "Each player is responsible for ensuring he is able to play in the game at the scheduled time. If he is unable to pay any bet, then he shall forfeit the game, and the game shall be played with a replacement. In the event that three or more players are "
They do not state how scheduling should occur, thus if the player agree unanimously they can start now. (as appropriate, the leagues usually run with ~2 week gaps between the start of each game, i think a delay is harmful to the format, but this is not specifically stated anywhere)
as for replacement, if all the top players* in the D leagues can be emailed the first to reply can have the place.
*top being those in the top 2 places of each league, therefore being the ones who are liable to be promoted at present.
IF we agree publicly (here), and there are no objections, i see no reason to delay or hinder the games.
that is to say, assume authority where it is not given. It is easier to ask for forgiveness than for permission.
