This is the best video tutorial on PG components for single project. Very clear and straightforward with a keen focus on the functionality of the features covered, but the accent is a bit thin 
i must say.
Looking forward to more details on the stuff you ran out of time to cover, like nested components which are currently vexing me pretty hard.
Also currently having difficulty with the backwards operation of converting an element into a component for reuse elsewhere. Would like too see that covered in a tutorial.
I was hoping this was going to cover Master Page functions, because you could have used that feature to quickly populate the other pages instead of dragging each library component item onto each page… but then you would have landed in the same nested component hell that i find myself at the moment.
Any light you can shed on my predicament would be greatly appreciated.
