I think we pretty much all agree that once a game has started and is underway, the Forum should play as little part in the game and how it is played out as possible. Games should be played with as little interference as possible. Certainly the consensus has grown up in the Strategy section, for instance, that discussion of strategy and tactics shouldn't be aimed at gaining an advantage in a specific game or situation by pooling the knowledge of a number of members. I've also had concerns raised with me that posts in Cheaters and Bugs, for example, are aimed specifically at altering a game situation rather than being what we may call "genuine".
The Admin/Mods have been looking at this. As a result, over the next few days you will see posts in Site Rules and various other forums which set out guidelines, policies and rules that are aimed at preventing games being influenced unnecessarily by Forum posts. When these go up, I'll post links below that take members to them. Although the underlying principle is not up for debate the guidelines/policies/rules will certainly benefit from your input: they're not set in stone and we hope they'll be improved by comments, questions and criticisms

What we don't want to do is prevent anyone from posting a genuine concern, either in-game or in the Forum, nor do we want to prevent discussions of strategy. I think instances in which players try to use the Forum as a tool in games are fairly few. But some areas need improving. For example, although the site policy will remain that in-game messages and Private Messages will generally remain private, messages that use the threat of the Cheaters forum to change a game are seeking to use a tool which should not be available. There's nothing wrong with asking players in a game to explain a questionable situation, but simply accusing someone of cheating or threatening a player with reporting them simply to change a game situation is using something outside the game to influence the game.

As said above, any input is much appreciated.
