Well, let me add my 2 sense, because it seems that you are making this a much bigger job than it needs to be. First of all, remember it's FAQ, not a grow book. It's just answers to frequent questions. The answers are in the forum posts, we've been writing them for a year, they just need to be compiled.
The purpose of the FAQ is so when we're answering questions in the forums, instead of typing in the same stuff, or referring to an old post, we can simply provide a link to the answer. It just helps to keep the forums clean, and easy to read, instead of long answers that most don't read anyway.
And with the wiki system, this info can be the starting point.
