I think a rule that in-game events can only be discussed once they are [X amount of time] in the past would be very helpful. It is fun to discuss events as they develop, but I do think most of the flaming or damage from OOC influencing IC comes from the OOC discussion of IG events and developments in essential real time.
Maybe things should have to be two weeks in the past before they can be discussed in the "Locals."
