Believe me, I have spent many hours pouring over the handbook, and whilst the information there is extensive, there are occasions where it is incomplete, not current, or inaccurate and sometimes it's not clear where someone should look for answers to a particular problem.
Apologies if I ask too many questions, but I've found this forum to be an invaluable resource for sorting out problems I encounter, some of which result from misunderstanding of the official documentation and most people here are far more knowledgeable than I will ever be and are very generous in sharing that knowledge.
