AOS is a friendly and relaxed place by intention. Efforts are made to ensure that remains the case. Of course there's the occasional 'hiccup' in proceedings and things get argumentative, but that's just forum life and an eye is kept on this to ensure nothing gets too unruly. The basic philosophy is to encourage folk to join in and not be put off saying what they think or feel about a topic. Seems to work well. Just my view!
