Had a similar experience with an organization I cofounded. An editor claimed it had to be bogus, that there was no way Yahoo!, Google, Microsoft, NASA, and the Worldbank would ever all coloborate on a social good project. Eventually we prevailed, but the article had to be insanely over cited to the point I feel it’s hard to read now and after the experience I’ve not felt it was worth it to encourage folks to maintain it.
I mean this in the politest possible way, I have no reason not to believe you, but all of your examples, GGP and down, would benefit immensely from a link to the contested revisions.
I think they just mean to post a link that points to the change you tried to make (and the subsequent ones). I think Wikipedia keeps a record of all the changes?
