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. See the Knowledge Base document Where can I find a repository of Usenet FAQ files? for help in finding FAQ files. A large list of all known FAQ postings in newsgroups is also posted periodically in the Usenet newsgroup news.admin.

RTFM Read The Fine Manual. This may be interpreted as: "You have asked a question which would best be answered by consulting the manual (or FAQ, or other help files), a copy of which should be in your possession. The question you have asked is clearly answered in the manual and you are wasting time asking people to read it to you." It's good netiquette to mail this type of answer to another user rather than post it in public messages.
