The normal rule with endgame proposals is that they should be submitted at least one adjudication ahead -- i.e., before the Summer retreats for a Fall proposal or before the Winter adjustments for a Spring proposal.  However, the Turkish solo proposal is in soon enough on Friday that -- what the heck! -- let's have a vote on Monday.
To pass, the proposal would require seven Yes votes, zero No votes, and zero abstentions (as I think you all know).  *Proposing* an end to the game does not equate to *voting* in favor of it.

Publicly submitted votes are official.  Of course, all players may subsequently reverse their votes in private.  As with orders, the most recent set is the official set.
Regardless, I will never make your votes
public, not even after the game.
Should the endgame proposal fail in the Spring, I will immediately adjudicate Spring orders.
