I find Geni to be a fast and easy way to build and share my Family tree with my family. They have tons of privacy setting to let you manage your profile and keep profiles of living and underage family private. By default, they do share deceased profiles with the public unless you mark the profile as private. As a non=paying user I find customer service is great along with the group of curators that are always willing to help you with your own profile, merging trees, or correcting tree info. Geni is a One World Tree as in there goal to connect everyone into one tree alone but as any tree building sites, there are some errors. With the ability to collaborate with others, it is not too hard to fix these errors and create a great tree to share and collaborate with your family.
