One newsgroup, News.answers , holds all FAQ documents from all newsgroups. FAQs from News.answers is a searchable archive. The University of Oxford provides collections of FAQs . You can either search the whole collection or browse by category or newsgroup. Keep it short.
Brief messages have a better chance to be read by others.
Phrase your question as specific as possible and maybe even tell people briefly what you already know. Trivial questions can be quite annoying and put people off a discussion. On the other hand, don't be shy asking if you have a serious question. If you have something to contribute to a discussion - please do so.
