Do I need good computer skills to use the membership website?

Membership provides video tutorials and PDFs of drawings. You're going to need to be able to navigate your way around the website to find the tutorials and download the PDFs at the very least. This will require having a computer or device that you keep up to date and a high speed internet connection. 

Membership also offers a whole interactive community along the same lines as Facebook, which does require that you have reasonable internet skills or are willing to learn them. But by no means do you need to participate in the community side of things if that's not for you or too challenging.
