Hellotree is a family social network, as well as an online family tree creation service and photo album sharing service. The family tree making tool provided by Hellotree is pretty good. After registration, you can add your parents, brothers, and sisters, and then each of them can add corresponding direct relatives. You can also share albums within the family and invite them to update the family tree. Hellotree doesn't provide too many functions, but it still feels like a warm family social network.
