Yeah I agree, both Ken and I are aware that the documentation is some what replicated, this is because several folks have generated it, worse still a lot of it is on the forum or places which aren't simply edited. A wiki may be a good solution, I have been working on a new home for the documentation and code on Github, maybe using Github's wiki might be a good place for this, however I worry about being able to move it later on. We would appreciate feedback from others on this who perhaps have more experience on such things..
P.S. Ken, Richard myself and other contributor do this part time when we get spare moment so it may appear a little in frequent at times depending on how busy our day jobs etc are, please bare with us..
