It beats me why anyone needs to be rude. It's quite possible not to answer a question at all, or to politely point out that as a quiz has only just been released, you'd rather not spoil it for others. Not thanking people for answering queries isn't acceptable either.
This site is about all kinds of people, young, old, clever, not-so-clever, black, white, fat, thin etc looking for answers, and people who don't like to give or receive them shouldn't be gratuitously rude about others, smug about their own accomplishments or ungrateful for the help they get.
Usual rules apply - if you don't want to know the score, look away now... or don't come here in the first place.
I'm not getting at anyone in particular or claiming that I haven't made mistakes in posting. I just think this whole exchange is ****poor and does no credit to anyone.
