Website and Blogs are adequate if you need information but sometimes you have a unique question that is best answered by another enthusiast. There are a wide variety of forums on the Internet where people will help you answer your specific questions.
An Internet forum, or message board, is an online discussion site. It originated as the modern equivalent of a traditional bulletin board, and a technological evolution of the dialup bulletin board system. A great deal of my initial knowledge of computer systems came from dial up BBS’es–to this day I remember the phone number of long-gone BBS’.
Now before you go off and start posting in a forum, you need to learn a bit about forum etiquette. My first bit of advice–read a few of the existing forum posts. Reading forum posts will give you an idea of the style of that particular forum (is it closer to a neighborhood club or more like a university classroom). Pamela Stevens has a good list of 25 Forum Posting Etiquette Tips that are worth reading.
