The Falls Church Wikipedia page is a good, instructive, and at times humorous example of how some attempt to manipulate Wikipedia.
In the latest edit, I particularly like how those wishing to remain in the Episcopal Church were “forced” out on the street, but now have “a gifted preacher and faithful priest” . . . who apparently found the time in the midst of all that faithfulness to supply – you guessed it – the latest edit to that Wikipedia page. :^)
