This thread is presently under moderator review.
Normally we would lock it until we have completed our review. However, appreciating the need of those among us who have been disrupted or potentially face travel disruption as a result of the events that unfolded over the past couple of days, an enormous amount of comfort can be taken by the very useful information posted here. Therefore we would prefer to allow the flow of information to continue.
So please remember, keep it clean and resist feeding the trolls.
Cheers,
Prospero
