This is a very short list of forums
that discuss, advise and instruct in web design, graphics, coding in all the languages, SEO, marketing, you name it. That's what forums are all about. A community of individuals who share their passion for and experiences with that forum's targeted focus.
There are many thousands of forums out here in the ether. Whatever your interest, I'll bet there's at least several forums that have started up just to help and support people with similar interests. I have many interests, so I belong to many forums.
I belong to all of the forums in that list above, just as I belong to about a dozen computer modding and enthusiast forums (and also have my own), a half dozen flooring related forums (my business for the last 33 years) and a whole bunch of other forums -- hotrod, health related, military veterans, political -- a long list. No, I don't participate in all of them every day. But, when I have an issue I need support on, I go to several of the forums I feel can help me the best.
This is all freely available, professional quality information. It's the wonderful thing about the Internet, and forum communities in particular. The website gamerfreak linked to, an excellent one too, also has a forum it has partnered with -- and they have over 30,000 members. It's generous for a member of a forum to want to help another, but sometimes the best help is to turn them onto hundreds or even thousands of other people who specialize in something no single individual can possibly cover in a short period of time.
To paraphrase you, to learn how to hand code HTML takes a lot more than a single individual could offer, but a forum could.
