Announce groups 6.2. Binary groups 6.3. Source groups 6.
Moderated groups come in many forms.
A brief description of the major types follows. Announce groups are generally specified as low-volume newsgroups that all readers interested in a specific topic may subscribe to. Some announce groups serve as a collecting point for FAQs and announcements for a set of related newsgroups, such as rec.music.info . Moderators of announce groups should make the charter as specific as possible, and should keep the focus on the value to the readers rather than the posters. Binary groups exist to distribute software.
