Jamie Nelson is the WikiTree tech who does most of the heavy lifting needed to keep the website running properly and who carries almost all of the workload to address bugs and make requested improvements. And she consistently maintains a pleasant and friendly demeanor in the face of the complaints and demands she gets from the rest of us (other WikiTreers are not always diplomatic when we describe problems that need resolution or improvements that we would like to see).
Since Jamie is a member of the Team, I know she gets paid, but I have a strong hunch that she isn't paid as generously as she probably deserves, and that much of her motivation for her work comes from her love for WikiTree. After all, she started out here as a regular member who probably had no inkling that she would be making WikiTree into a career!
Jamie Nelson is truly a Wonderful WikiTreer for all that she does here.
