Well nanatobe (congratulations and welcome, by the way), all I can say is to keep in mind the advice I had when training as a teacher many years ago: 'the most important thing to remember is that when you go into a staffroom for the first time, don't sit down until everyone else has, otherwise you could be sitting in someone's favourite chair.'. In other words, it is very easy to upset posters on here by transgressing unwritten behavioural rules and then you will get a combined unexpected attack. One of the first posts I made involved the lighthearted use of the word 'flouncing', which was often used in a teasing way on other sites I belonged to - the person I used it about said that she had never been so insulted, others said that it was the nastiest comment they had ever seen!
