Wikitree is an excellent free platform to collaborate with relatives near and far on a global family tree. The vision for having one profile per person who has ever lived means that budding family historians do not need to reinvent the wheel when researching their family history, and get the benefit of work done by others across the globe. It is exciting to be able to join in projects and collaborate further. I have particularly enjoyed participating in the Appalachia Project and the England Project. People are willing to give their time and talents to work together to meet the global goal. I have found standards to be very high indeed and it has been an absolute joy to be a member of this site.
