It certainly was :)

I really am abysmal when it comes to grammar terms, I can just about handle 'verb' and 'adjective' and there it ends. Towards the end I was getting a bit lost as to which part of the sentence the terms related to, which was why I really appreciated the explained examples as, even if I didn't know the exact terminology, I could still see what was going on and the kind of rules being applied - if that makes any sense.
