Hello, I seem to have sent out the survey in a manner that only allows a single response per email address and I sent it to the list serv address. Looks like Paul Manos was the first one to start the survey and all I see are his responses. I will follow this up with a weblink where you click and each person can respond separately!! Sorry!
