All orders must be passed IG/IC. You can't punish someone IG for things done OOG, or for not doing things IG that are discussed OOG, etc., etc.
I disagree, because according to that, you can organizate a rebellion OOG, and joining the underground at the same time. 20 nobles joining the underground, being at the capital and starting a rebellion at the same time is not fair play, in my opinion. The ruler would go mad, because he checked the underground a few hours before, because there were a lot of untrusted nobles sitting and rallyiing in the capital, but "nobody" was there.
I am against OOG talkings about strategies, because you will use them IG. I could arrest and torture the Generl of my enemies, but I couldnĀ“t find any kind of information with him, except for the orders he gave to the MArshals... but .... he talked with the MArshals about the plans for tmorrow ( OOG obviously ) because the player behind the General will use that OOG conversation IG.
