Each FAQ is posted to comp.sys.sgi.misc and to the and newsgroups (whose purpose is to store FAQs) twice per month. If you can't find one of the FAQs with your news program, you can get it from ftp://viz.tamu.edu/pub/sgi/faq/ ftp://rtfm.mit.edu/pub/usenet/news.answers/sgi/faq/ (rtfm.mit.edu is home to many other FAQs and informational documents, and is a good place to look if you can't find an answer here.) The FAQs are on the World Wide Web at http://www-viz.tamu.edu/~sgi-faq/ If you can't use FTP or WWW, send mail to firstname.lastname@example.org with the word 'help' on a line by itself in the text, and it will send you a document describing how to get files from rtfm.mit.edu by mail.
