Yeah, Camonk is right. I remember when he was originally featured on POEtv and I scoured Youtube for any other lectures to watch. Don't remember this one, so it's probably new.
I submitted this with his other three videos back when the hopper only required five votes to approve a video but you still had to wait the week out before they were on the front page. For whatever reason, the fourth video didn't make it out at the time but the other three did. I just wanted to try again.
