I'm sorry that no one has responded to your question yet. There's likely two reasons: (1) many of us are currently engaged in Wikimania'14 and (2) the timing of discussing a new subject recruitment request is tense due to an ongoing discussion about how external subject recruitment requests should be handled on-wiki.
Whatever conversation is happening about the current process, there is a common practice that I recommend following for running your research on Wikipedia. (1) document your research proposal on meta and (2) engage in a conversations with the Wikipedians about your study to make sure that you won't inadvertently cause. If you reach out to me and/or Dario, we will help as much as I can. You've been through this process before, otherwise, I'd give more specific instructions.
