I agree. I spend decades helping DAR get members because I was learning to research. I live close to DC and spent about 3 days a week at either the DAR library or at the National Archives. I was working part time, going to graduate school and raising a family. I did this because I loved it. Sadly I was rarely thanked and after several decades I stopped volunteering my time. By then I was a hazard because I could spot a questionable line and knew the tools to find supporting documentation. If the line worked out for the applicant, every one was happy. If it did not, I was not thanked and I really did feel badly.
I truly understand why an applicant is going to disappear after the delay and disappointment.
