I have answered quiz questions on here in the past.
I did not know they were from a quiz with a far-off closing date.
In fact, I often did not know they were from a quiz at all!
Or that setters had asked the participants not to seek help early on, or at all.
Having said that, I have had a look at the posted questions today, and there is nothing hard about 53, 84, or 100.
I liked 100!
I can not see 6, so far.
