Perhaps doing it online in a wiki form would help, it spreads the workload out and can be imroved by more people that way.

I agree that most people just want something to work, but the number of horror stories and people getting hugely stressed about things not working and not understanding why they don't work I think shows that such a resource would be useful. While ploughing through the forums I came across a similar sentiment of "If a machinist can't fix his own machine he isn't a machinist". People don't really decide to build their own car without expecting to learn about being a car mechanic and how internal combustion engines work so why try to reduce cnc to the level of understanding that is required to assemble a table from Ikea?
