I've always been impressed by the wealth of knowledge this site's members possess. Collectively, it is one of the great think tanks in the 12 volt industry. Many of you have noticed that often when a question comes up in the forums on a particular subject matter, that you are ultimately the one who answers it. You are not challenged for accuracy, the poster understands the answer and other members tend to step to the side to let you field the inquiry.
As much as you may be hesitant to acknowledge it, you are an authority on that subject. You should spend some time writing a paper on the subject matter and post it in the forum, covering the particular subject as completely as you can. Whether it becomes a featured topic is not the important thing; it will be a thread that you (and other members) can link to when another of the same ol' question comes up. The new reader then gets the benefit of your knowledge in a more complete way, using the information in the link along with your unique input into his particular problem.
Look to some of the featured (stickied) subjects to get an idea of how to put it together. Basically, a part of a subject, or a sub-topic, can be written about in detail in one readable paper, where a broad subject matter cannot. For example, Dan Wiggins (Adire) wouldn't write a paper entitled "How to design speakers", but he writes papers on certain aspects of their design. You should answer the questions: who, what, why, where and how. Tell the reader what you mean to say and what they should learn. Acknowledge sources, and introduce your own unique view and personality into it.
This is also something that can be done in other's threads, as responses, but in smaller bites. You can still use your past responses to help a new reader by linking to them. You should find that a gradual buildup of detailed and well-thought-out answers in forum threads will, over time, provide the material for your write-up in the future. After you have continuously researched the subject over time, you will have built a source reservoir. You will be writing as an authority on the subject, acknowledging your resources and providing your own personal opinions about it. By that time you will realize that that's what you are.
