by and large taken into account since then, I think. I would like to add that that courtesy has been extended, more than once.

My post simply referred to the darwinian nature of "a challenge" - to misapply the Biblical quote, it comes down to the quick and the dead. If someone posted a challenge at, say, 03:00 NZ time, I would never expect others to defer answering until those sleeping were awake. I know that there will be many times when others will be able to respond to a challenge faster than I, so, when I have the chance, I shall seize it. You should see me at the dinner table!
