Trying a different approach

Seven email interviews went out, and only two came back.  I thought I would be easy on my participants, and send out two interview emails with a few questions on each, and got two responses from the first emails sent out - but none after that.  After a few gentle reminders, and a pilot study assignment coming due, I decided to do what I probably should have done in the first place and will be going in to do the interviews in person.  This is not how I envisioned my research project going, but oh well.
