The History of LUE - Probably the first place you should go if you're here. That's why it's first on the list, you see.
Squeak's Domain - Has some more info on the LUE's history, plus some archived topics.
LUE Map - According to this, we're most concentrated in the US. And everyone blames Bush...
GameFAQs Info - One of the most comprehensive GF sites (it has LUE stuff, so don't get all dumb).
You know it.
GameFAQs ASCII - Exactly what it says. But they help you and stuff too.
LUE Online - An web-based RPG. I've never actually, y'know, played it, but I bet it's cool.
