I'm not certain about that. I'm pretty sure that was the original intention.

[quote=Tinpan] If so , I went to an Anders blues one and the whole course was there. I guess what I'm wondering is how much of gt is available for free out there to non subscribers

That is surprising! The entire blues course is on YouTube? Or on some free site?
