See https://wikitech.wikimedia.org/wiki/Talk:Volunteer_NDA , which includes a prototype in phab-01.
So far we are handling volunteer requests requiring NDAs on a case by case basis. We tried to setup a process based on RT, but it didn't work. Phabricator should be better suited for this task.

 Update https://wikitech.wikimedia.org/wiki/Volunteer_NDA to document the new process
 Test the process with a first volunteer, real case or not.
