It is. That's why money is charged. Also, that's a reason there are lengthy free articles on the website. It seems with almost all blogs and completely free sources, people are kept dependent and never get all the way to very knowledgeable about style themselves. Also, because 'noobs' often can't tell good from bad, this thread does a public service, even if it's mean at times. A good forum is maybe the one free source where, occasionally and after a long time of active usage (plus probably some mistake purchases), a person can become almost a style expert.
