I don't need a certificate to know I'm good at what I do. I've taught myself all I need to know, and I'm proud of where I am, and my skill set.

There is much more to learn though, not all information is available for free.
Maybe the Library but who in the heck wants to read a 3000 page book.

Actually, I have textbooks and all the crap they'd use in courses. I'm not the skid who learned from TUTs on HF. While there may be a benefit to learning from a teacher, who do you think taught the first teacher?
