As much I'd love to have 4D on Wikipedia, I honestly don't think that it's possible.
There seems to be a small group there, who have taken as their personal crusade to wipe out all textmuds that try. Severals of those had a lot bigger pbase than we do.
The flamewars about this, for instance on TMS, have been pretty nasty.
Just to give one example; I doubt that articles on the subject of Textmuds posted on a site for Textmuds would even count as a reference.
We could try, of course, but don't get your hopes up too high. I've seen several much bigger muds try and get erased for their trouble.
One possible reference however could be that we are one of rather few Muds who got an "Official" revue on TMC. At least THEY are on Wiki...
