Actually, it looks to be 4 rounds staled. Or at least 4 rounds with no troop buys.
I think it is unlikely that the other player does not use this forum, or at least check in at Gandalf's blitz site. How else did he/she find out about and sign up for the game in the first place?
Changing the port back is unlikely to help at this point. If the other player is truly out of the loop, they he/she has probably punted on the game. I doubt they will check back in.
This is a real bummer. I was recently in another of these blitzes that had to be terminated due to lack of participation. We could ask Gandalf to switch arco to AI, but then we would just have a 2 person game. Not sure that is your cup of tea - definitely not ideal.
Whatever you decide is fine with me. As Gandalf said, you start the thread, you run the blitz.
