Thanks for the ideas, all of which are good. I've done the nursing school bit with little success. It's been kind of hit and miss with the leadership body route; some people were responsive, others not so much. Still though, not much success in terms of enrolled participants. I think you're right about some online skepticism, so, yes, this would seem like an ideal place to recruit. I'm new here, so don't know if this is ok. Would it be kosher to post recruiting announcements on the various forums here?
