I also disagree with this. It applies to some games, but not to all. Take, for example, any game in which the roles are known beforehand. There aren't twists, so that's not a problem. For miscounting, if you think it *might* be twilight (because someone else said so, or whatever), is it that difficult to do a recount yourself? In Minv4, it wasn't a rule, but if it *had* been a rule, then it would've taken you a couple extra minutes to check and see that CB had gotten the count wrong; posting while you aren't sure would be a violation of the rule. Not one I would modkill you for, but one I, as a mod, would be annoyed about.You SHOULD NOT disallow twilight posts for many reasons, not the least of which, the players often mis-count. It also eliminates several interesting possible twists (like players that take extra votes to lynch, and many more).
I guess the point I am trying to make here is that the players do need to keep up with such things (it makes for a better game). In the live version you don't have this problem, the player is dead as soon as he/she has a majority, because the mod is always there. The death occurs at majority, *not* when the mod says so. Obviously there are variants that need a "twilight" in case something screwy is going on, but not all games do.
I'm pretty sure there are some possible things that can go wrong if you allow twilight posts all the time, but I don't have time to think about it at the moment (meeting with advisors, whee).
