When the lawyers turn up at your door, or start sending TF threatening e-mails then you should deinstall in and go out and buy MGE or whichever patch it was you were using.

Similarly, the city of Chester in England has an ancient law that states the citizenry can only shoot Welshmen with a bow and arrow within the city walls and after midnight, whereas Hereford folk are not allowed to shoot Welshmen on Sundays with a longbow within the Cathedral Close. Elsewhere in Hereford, with other weapons, and at all other times, therefore, we must assume that the shooting of Welsh people is entirely legal.
