Haha I actually missed the part about Fierying people, thought it would just be a subbie where only 10 people could post.
While I can't reveal what the challenges will be, partly because I haven't thought it all out yet, I can say that it won't require super activity like the mafia games, but a minimum amount will be encouraged.
I'm saying if you're inactive you're not going to be of much use and I'll encourage your tribe to vote you off.
Don't make it a choice. Winner gets 25,000 posts added to their count. Runner up 10,000 Everyone else gets banned, timeframe ranging from permanent to one day, depending how long they last. Any PM/VM to those outside the house results in instant eviction.
