Thanks Abby, you're the best! As I expected, the fewer people in a theme, and less US centric, the less interest is shown. Not to be mean about it but, if you feature themes where the least known genealogical participation is expected, you will find the theme that garners the least interest and participation. To expand the Tree, my thoughts are to find the theme that generates the most interest and participation, whatever that may be. As a voluntary participant in genealogy, my participation does not depend on inclusivity. Some of my most interesting discoveries are met with indifference when shared with people that have no interest in genealogy.
