FAQ:Frequently Asked Question. When people say "the FAQ", they are generally referring to a list of answers to Frequently Asked Questions. These are posted monthly on many newsgroups or mailing lists to reduce discussion of topics that have already been thoroughly covered. It's a good idea to look at a FAQ file for a newsgroup or mailing list before participating in it. For help in finding FAQ files, see the Knowledge Base document Where can I find a repository of Usenet FAQ files? A large list of all known FAQ postings in newsgroups is also posted periodically in the Usenet newsgroup news.admin.
