Now search for postings dealing with the particular subject in which you're interested. Deja News will find all similar newsgroup postings. You will find dozens and dozens of newsgroups where the focus is helping users solve computing problems. It's best for you to find a newsgroup that is as specific as possible to match your problem because you will have a better chance of finding experts in that particular area. However, you have no guarantee that the person responding to your question is an expert.
Some postings never receive a reply, either.
Because of the large number of newsgroups available on the Internet, we can not make specific newsgroup recommendations for each specific problem. However, we will help you match a general newsgroup category with a focus area. You then can search deeper into the category to find more specific topics. For instance, under the comp.sys.ibm.pc newsgroup heirarchy, you will find several more specific newsgroup subtopics, including hardware. You can be as specific or as general as you want when choosing a newsgroup.
