I really like this site and the people that play here. I only have one issue with one single option. You guessed it. The ON VACATION option. I have four of my games where my opponent is on vacation and three of them are clear wins. The other problem is that they all say my opponent has 0 months and thirty days of vacation ALL THE TIME and it never changes.
I think that prior to going ON VACATION there should be some kind of computer analysis and if the win is imminent, the win should be awarded before the other player can use the vacation option, especially if they have they have the option of using it indefinitely.
