A meme page would be good. Give me some clarification though, are you wanting this to be something where you TEACH guitar or discuss guitar. If it’s teaching, then maybe a place where we can request specific tutorials or topics for you to make videos, etc. on. Just a thought as you are going to have people, all at different levels of competence, and you won’t have any way of knowing what that is for each of them without 1-on-1’s or a request page.
