Correcting/editing a well written text, even if erroneous, is generally easier than writing a new text. Errors and misconclusions can always be omitted from the end result.

Generally, it takes a few iterations to come up with a good text. In this case, it would be best to take the player contributions as your raw material and compose the FAQ based on the player contributions, combining multiple player-written FAQs with overlapping information. If you write a new FAQ instead of correcting someone else's, you'll make the mistakes of the new version and the end result is generally worse than what a second iteration would be, providing that the first was well enough written. I think that edited and combined versions of the player FAQs would be most beneficial to the newbies, providing that the Immortal staff is ready to put some work in it as well.
