How do I become a member?

I know this is a general question, and maybe very obvious, but it brings me lots of problems. There are some pages on toonboom.com that I can’t see. It says: “This section is for members only. You are not authorized to access this section”. What does that mean? How do I see those pages?

I believe that applies to the fee based support section under Supporting Excellence:
