let us say there is something you don`t know how to do.in the past if you were determined to learn, you might have called a friend or a relative, taken anight class or walked down to the local library for a research term. but now a host of websitos are sprinoing up to provide free practical advice on these subjects and actually anything else you can think of.
in one sense, these "how-to" sites represent the growing world of on-line loarnino. this tradition found one of its earliest forms in the fags frequently asked questions files that began on usenet, the internet`s global discussion group.the fags, many of which still circulate (go round continuously), took a specific subject and explained it to complete novices.
but "how-to" sites take the faqs idea in a somewhat different direction by addressing subjects that aren`t necessarily related to discussion forums. these sites take the style of a written tutorial (teaching period) and a tone of friendly advice. possibly the biggest and best known of these sites is learn2, com (www. learn2, com). it offers nearly 1,000 free tutorials and adds new ones frequently for a job interview. at ehow. com you can learn how to train for your first marathon, how to buy a vacation home, or how to make a movie in eight steps.
