A monthly magazine, called Linux Journal, was launched over four years ago. It includes articles intended for almost all skill levels, and is intended to be helpful to all Linux users. One-year subscriptions are $22 in the U.S., $27 in Canada and Mexico, and $32 elsewhere, payable in US currency. Subscription inquiries can be sent via email to subs@ssc.com, or faxed to +1-206-782-7191, or phoned to +1-206-782-7733, or mailed to Linux Journal, PO Box 85867, Seattle, WA 98145-1867 USA. SSC has a PGP public key available for encrypting your mail to protect your credit card number; finger info@ssc.com to get the key.
There are several Usenet newsgroups for Linux discussion, and also several mailing lists. See the Linux FAQ for more information about the mailing lists (you should be able to find the FAQ either in the newsgroup or on the FTP sites).
The newsgroup news:comp.os.linux.announce is a moderated newsgroup for announcements about Linux (new programs, bug fixes, etc).
The newsgroup news:comp.os.linux.answers is a moderated newsgroup to which the Linux FAQ, HOWTO documents, and other documentation postings are made.
The newsgroup news:comp.os.linux.admin is an unmoderated newsgroup for discussion of administration of Linux systems.
The newsgroup news:comp.os.linux.development.system is an unmoderated newsgroup specifically for discussion of Linux kernel development. The only application development questions that should be discussed here are those that are intimately associated with the kernel. All other development questions are probably generic Unix development questions and should be directed to a comp.unix group instead, unless they are very Linux-specific applications questions, in which case they should be directed at comp.os.linux.development.apps.
The newsgroup news:comp.os.linux.development.apps is an unmoderated newsgroup specifically for discussion of Linux-related applications development. It is not for discussion of where to get applications for Linux, nor a discussion forum for those who would like to see applications for Linux.
The newsgroup news:comp.os.linux.hardware is for Linux-specific hardware questions.
The newsgroup news:comp.os.linux.networking is for Linux-specific networking development and setup questions.
The newsgroup news:comp.os.linux.x is for Linux-specific X Windows questions.
The newsgroup news:comp.os.linux.misc is the replacement for comp.os.linux, and is meant for any discussion that doesn't belong elsewhere.
In general, do not crosspost between the Linux newsgroups. The only crossposting that is appropriate is an occasional posting between one unmoderated group and news:comp.os.linux.announce. The whole point of splitting the old comp.os.linux group into many groups is to reduce traffic in each group. Those that do not follow this rule will be flamed without mercy...
