I've said this before but I think for free lessons its hard to beat Justin Guitar. He covers so much stuff. At the moment I'm following the practice series but his other series are brilliant & I wish I had his beginners course when I started. I just wanted it as a link as if anyone is looking to expand their playing its worth exploring

I've followed a couple of his lessins and I agree, I think they are really good - certainly could have done with this when I started.
