Welcome!
I've recently transitioned from a site built with GedSite, which would take my Family Historian data and place it on a website. It's a great program, and I would recommend it to others. However, the generated website did not allow me to let others edit their portions of the family tree. TNG, on which this current site is run, does allow for this kind of community-based genealogy. So with TNG other researchers, after I approve their request for an account, can login with a username and password and make changes to their part of the family tree. The URL for the old site, now redirects to here:
