You are quite welcome, Batman. Even if you are from a council estate, I am more than happy to discuss this with you as there are worthy people from council estates too. You and I and others too. You are into books, so may I recommend Lightbown and Spada's "How languages are learned". It is an excellent appraisal of both 1st and 2nd language aquisition. For Beanz I recommend "Politeness: Some universals in language usage". I feel it may come in useful when it comes to his online posting style.
