I am the founder and admin of the Mutant Future Wiki. I made that wiki as a place for anyone to throw their random ideas and house-rules in one place. I have done a lot here, but supporters have been few and far between.
A Labyrinth Lord Wiki would be cool... Or better yet, a combined retro-clone wiki, with each article noting which system they are used in. It would be a great place to compare the systems, so players can choose which rules works best. I have been trying a multi-edition approach like that - from 1st to 7th, with notes on MA - with the
Gamma World Wiki (but that wiki is in constant no-fan-support limbo, which is a shame, as the supplements and models are full of neat creatures and items.
).
