To be fair the same post did advise a visit to the DT. But I was more than a little hurt to read the above. It was a bit like someone else criticising your children, Ok for you, as the parent to do it - Whatever their faults, hearing others doing this will put you right into defensive mode.
I'll take a polite Mudcat duffer any day, in preference to a conceited poster who is under the impression that they hold a monopoly on "real knowledge".
