3. What Netnews Is
Netnews is the set of people who exchange articles tagged with one or more universally-recognized labels, called "newsgroups" (or "groups" for short). There is often confusion about the precise set of newsgroups that constitute Netnews; one commonly accepted definition is that it consists of newsgroups listed in the periodic "List of Active Newsgroups" postings which appear regularly in news.lists and other newsgroups.
(Note that the correct term is "newsgroups"; they are not called areas, bases, boards, bboards, conferences, round tables, SIGs, echoes, rooms or usergroups! Nor, as noted above, are they part of the Internet, though they may reach your site over it. Furthermore, the people who run the news systems are called news administrators, not sysops. If you want to be understood, be accurate.)
