Ashley - I would send another email -- to share some research you find about something related to the company or organization. It is a chance to keep your name in front of them. Again say how excited you are about the opportunity and why you are specially qualified for the job.

Sas...I've think I've mentioned this but...a year ago my husband faced the same thing. He was turned down as too qualified. He went back and asked to speak again. Explained why he wanted a job for which he was "over-qualifed" and why they should hire him. And they did.

If they told you that....send an email...Over-qualified vs under-qualifed - which is better? Light-hearted but pointed -- better work ethic, able to handle emergency. Maybe list the reasons people fear over qualified - want too much money, going to quit as soon as something better comes along, will want my job - and give a response to each one.
