MadameCurie I see this everywhere in every conceivable subject area. It doesn't matter how many times the same question is posted, it gets asked over and over again. It's just something we have to live with I guess, since in most places you're not allowed to say 'for goodness' sake this was just posted 5 times yesterday, do a search first! or even just scroll!"
It's one of the banes of life on the internet.
