The OP now appears to be doing his ironing.
I am merely pointing out that it isn’t constructive to read a thread, and then contribute nothing other than point out someones spelling and grammar.
…and how do you know with your vast experience that such people might be a tit on that thread, but hugely informative on others? Some of the most irritating on here do actually contribute a vast amount to our community (I’d argue that was certainly the case for one of the long term banned). What exactly do you bring to this forum?
I should point out that I have particular cause to be grateful for the expertise available on here – possibly more so than anybody else.
