I will post this in as plain and clear English as I can.
I want you to post exactly what you know about xorxes' role.
I want you to do so about thirty seconds before night ends.
This gives everyone the knowledge that you actually know what xorxes role is.
It also demonstrates that you knew BEFORE xorxes potentially dies tonight.
This helps prove your claim.
This is in your and the town's best interest.
Failure to do this brings doubt upon your claim to the town at large, even if I think you know, the rest of the town doesn't.
