In the same way that you find smart matches within other family trees on your site, it would be a spectacular feature to automatically run searches on all available data bases for every person in a tree and alert any matches. There are so many data bases, census and other sources where you offer search options in your research area which would take very long to search for every person in the tree. It would be nearly impossible logistically for a manager to run a search for each person, inventory searches done, and keep them updated with all the databases. If this was a proactive feature in which you ran those searches regularly, it would be a researcher's dream. tx!
