It is a rule but I'm normally flexible as I keep an eye on things and make sure that no advantage is gained by posting or editing late, and nobody has complained or argued about it yet. However if any of the players want a rule to be enforced then I will do, since it is a rule after-all; and you appear to be requesting a strict deadline now blueberry so I will adhere to that from this day onwards.
So to confirm: all entries posted after the allocated deadline will not be counter and all posts that have been edited in any way after the deadline will be disqualified.
On another note: damn you Anderson winning in 2! Very bad result for me
