Excellent book about efficiently managing joomla, I also had some difficulties, the rhythm or will some reviews we could blame the book does not teach us to use Windows before joomla attacked. We do not all have the same kind of intelligence, seek edition that suits you. No textbooks exactly treats even when some items are not treated at all. That's why I buy at least two books when this is not three (books and videos) for a Master which I consider correct.
