Just so people know the official position:
We considered password protecting the LS/DS threads to prevent people looking at each other's plot, but it would have been inconvenient and would also have prevented onlookers from seeing what the game was like, and we would have less players.
In the end, I decided to let people do what they like. You can either keep the surprises or you can read what the other guys are up to. So long as your character never says anything like "Hey! I bet THIS is what the other guys are up to, and so we can stop them like THIS..." (obviously, showing knowledge from the other thread) then I do not mind.
Meanwhile... this thread seems quite popular, but only to concerned parties. Should I set up a General Discussion thread in the RP area where you guys can chat and taunt at each other?
