It is very hard to convey emotion in text, and I don't think many threads are posted to be as harsh as they often sound. Local meanings often vary.
That said, we are known as a helpful community, and we should do what we can to assist, otherwise there is no point in being part of a forum.
I do appreciate the frustration though. Many new comers do ask question for which a simple google search would provide many simple answers, and it does come across as lazy. That said, newcomers may want to post something, to get involved, and these are the only topics that spring to mind.
So, please, let's try and be helpful and, as Marge Simpsons mum once said, "if you haven't got anything good to say about anybody, then it's best to say nothing".
