Halloween marks the birthday of something other than Peter Jackson, though aniversary is possibly a better term. Today is the birthday of the Nightmare LPMud. On the Nightmare LPMud is where I met Calisuri, where some of the original planning for TheOneRing.net occured, and some of the early TheOneRing.net virtual meetings took place there.
The Nightmare LPMud can be reached by telneting to nightmare.imaginary.com 1701. You can read more about the Nightmare LPMud and muds in general here.
Now as a side note, if you are interested in finding out what Nightmare is like normally wait until Monday. Halloween has long had a special significance on Nightmare.
