As for discussing games in progress, I think there were a few variant games here recently that dealt with that. I think the reason for the prohibition (I'm not sure if its a prohibition or just considered bad form) is because the game is supposed to be a match of wits between 7 players. If each of those 7 players was asking the community for advice, then whatever country is strategically best would win (If a computer ran all 7 countries, what country wins most frequently??) Personally, I like the idea of learning from my failures, but even with getting advice, talking to other players is more than half the game, convincing or threatening them, etc, so even with getting advice, not sure how much good it actually does you. Getting advice, or talking about ongoing games, would seem to work well only with gunboat games.
