I believe that nob ody was left with a country they positively didn't want!
As usual on this site, the first turn (initial builds) runs for double time, i.e. six days; but my experience is that players in Forum Games don't need this long and are keen to get on with the very different game. So what I propose is that there is an absolute deadline for initial builds at 14.00 BST (0900 EDT) on Monday 13 June, but that there is a provisional deadline of four days, i.e. the same time on Saturday 11 June. I will give approximately 24 hours notice of Saturday's deadline, and at any time before Saturday any player can request that we run the initial negotiation period for the extra two days (I don't mind if somebody writes immediately asking for it!) Post the request here so that everybody sees it please; it will be automatically granted.
Finally, if anybody needs deadlines expressed for a different time-zone please let me know (not too many if you can avoid it!!)
