A number of newsgroups are devoted to Lovecraft and his creations, most notably alt.horror.cthulhu.

Lovecraftian topics show up frequently in this newsgroup dedicated to a broader range of horror. The Alt.Horror FAQ is maintained by Christopher Nauta.

This is the primary newsgroup of interest. The topics of discussion range to anything Lovecraftian or Cthulhu Mythos related.

alt.horror.shub-internet

An odd newsgroup whose exact purpose is unknown to any but the secret initiates.

alt.necromicon

This newsgroup is theoretically devoted to discussion of Lovecraft’s Necronomicon, yet its traffic is slight. The misspelling of the newsgroup’s name is deliberate.

alt.necronomicon

Finally, someone got around to fixing the spelling of this newsgroup’s name. Like the other Necronomicon newsgroup, the traffic is slight.
