I got a reply from Dr. Knox! Unfortunately, under the terms of her agreement with her publisher, she can't opt to give away a copy of her own work.
I shall follow-up with a letter to her publisher.
In the meantime, here's her reply, with just a couple of redactions to protect the guilty:
Dear Mr [Natas],
Thank you for your email about my recent article in the Journal of Religious History. I am of course aware of the discussion group Jehovahs-Witnesses.net and of the vigorous debate on a wide range of topics which the forum facilitates.
I have received several requests regarding posting the article online by the members and moderators of a number of online communities. I have read carefully the terms and conditions issued to me by Wiley-Blackwell, the publishers of the Journal of Religious History. Unfortunately, the publishers have advised that I am not permitted to give consent to third parties to post the article online.
If you wish to pursue this further on behalf of the members of Jehovahs-Witnesses.net it would be best to contact the publishers directly. The Wiley-Blackwell Rights Department can be contacted at [redacted by NN]@[redacted by NN].com . The full bibliographic details should be cited in the request, as follows: Zoe Knox, 'Writing Witness History: The Historiography of the Jehovah's Witnesses and the Watch Tower Bible and Tract Society of Pennsylvania', Journal of Religious History 35, no. 2, (2011), pp. 157-180. If the publishers decline your request to post the article to Jehovahs-Witnesses.net perhaps the forum's members will be able to access it elsewhere. The Journal of Religious History is a well known periodical with a wide circulation. Many libraries around the world subscribe to it either in hard copy or through online journal databases.
Thank you once again for your interest in my research. Please accept my apologies that I am not in a position to grant the permission you have requested.
Kind regards,
Zoe Knox
