I wasn't sure where to post this. I thought it might go under resources or maybe something linked to education.
I was hunting around the internet for permaculture reference material and I came across an Itunes University video course series. It is like a distance learning class recorded from NC State and Dr. Will Hooker. The course is free. And, I think it is pretty awesome.
There are 38 videos. The quality is really good. In the ITunes University I searched permaculture. It is listed under the course HS 432 (maybe that search on iTunes university might be easier).
The only thing you don't get to do is ask questions. I picked up several of the books listed as the class materials from my library and read my homework prior to each class. I am about a third of there way through and thought I would post in case others want to do some self-study.
