Finally got around to watching this, WOW!
If you have not watched this highly recommend you do so.
Has many Q proofs and also explains the meaning of many Q posts that have not been explained before (that I've seen).
Recall someone suggested MoD add this to introductory stuff at the beginning of the Q treads, a great idea IMO!
