I have an idea, why don't Host makes a Reward for those who can write a Good Summary about the game every 50 Pages
Not only it would encourage Players to write the Summary, but those who are inactive can always catch up
Also this System would make the active players have more advantage than inactive ones, which is good cuz those are giving time for this game, while most others are not participating much (And most the time, they are Scum, so it's another reason to force them out of hiding)
