Our EB house rules specifically allow anyone (alive, dead, or spectator) to speculate in this thread. Except as mentioned above, you can not share your role or information learned from that role not already mentioned when alive. Some dead players elect to not speak about the game after they are killed.
I'm not sure how the tournament operates post death. I don't recall seeing any rules about it, but I'm going to err on the side of caution and assume that I can't discuss anything post death.
BTW, the tourney starts for me at 8PM on Monday.
