I’ve put up a detailed LegendMUD entry with a bunch of citations. Yeah, it’s a conflict of interest, and I am sure I am misremembering stuff or letting my bias show. But it’s also the only way some of this history will be preserved.(And wow, I had forgotten a lot of this stuff!)
Go there, and jump in, and help. And hey, if people do the hard work of finding sources and the like here, then some articles can maybe migrate back to Wikipedia.
