I'm surprised no one seems to have mentioned that
Part I, question 6 of the
Form 990 which asks for total volunteers. For year 2011, 85,000 was the
number year 2010 has 100,000.
That's just the number of editors taken from WikiStats, as I believe the
notes to the actual form 990 explain.
You may have missed "the movement" in the subject line; the form 990 is
only about WMF properties.
