The last thing I will add to this (cause Im cant think of anything else sensible to say, and I dont often do sensible) is that you can always be assured that if Admin or a Mod do lock a thread, there is always a very good reason. The reason may not always be obvious to members of the site, but it is always done for a good reason and for the good of the site.
However, as I said, we are human (well apart from Sarge) and if you feel that a thread should be unlocked, then get in touch, either via pm to the Mod or via the Contact Us button over there <<<<<<< The locked thread will always be looked at and discussed.
My personal opinion is that if I see that a person is heading to the airport to catch his/her flight to banned island and I can gently persuade them to watch what they are posting so that they don't get out the taxi.. then I will do so.
I look upon my roll here as primarily a guiding and helpful one not a chastising one, all us ops and mods feel the same way.
We would rather help and guide members than ban them.
