I occasionally receive wikitree feeds in my email. As my usual method of research (before I found this site) was to start with most recent person and work backward, I landed on a tree that's managed by a few people, but not the person listed as the updater. As I have a couple of generations I can contribute to this tree, who would I send the info to- the person listed in my email as 'edited biography,' or someone who's managing the tree?
