I might just pop in and say we're very, VERY lucky on these forums. The vast majority of members are mature, helpful and accomodating.
While its easy to think people are having a go, its probably worth noting that on SAU people are usually *not* having a go (or if they are, its more obvious and they're likely just taking the piss).
(Oh, and as a side note, we have a lot of female members too. Theres no sexism or assumed knowledge.)
Enjoy the forums.
