Some newsgroups that have more or less existed at some point in time, but whose existance in the current point is not known include the
gnu.emacs.sex for those who truly feel passionate <3 <3 <3 about their most favourite editor and legendaric
comp.talk.emacs.recovery for those who’ve come to notice their passion’s grown wrong.
Some of the EmacsNewsgroups are also available as mailing lists, in addition to the actual, real, proper EmacsMailingLists. And vice versa. Generally it is better to read and post news. Some of the gateways don’t work too well, however. When reporting bugs, for example, make sure you use the M-x report-emacs-bug command instead of posting to the newsgroup.
One bidirectional gateway is Gmane. Emacs has it’s own hierarchy there called
gmane.emacs, most of which the Emacs-related lists populate. Its directory is at http://dir.gmane.org/index.php?prefix=gmane.emacs. Some lists have been categorized differently though, for instance the MH-E groups are under the
gmane.mail hierarchy. Use the  Gmane search facility if need be.
