Finally got the chance to check out Geni. Creating a family tree was so easy. As is mentioned on their site, they have a great "fun simple interface" so adding siblings, parents, and kids was really easy.
I didn't even need to sign up to create my family tree, though I did in the end. Geni is a private network, which means that only the people in your tree can see your tree and your profile.
Not really useful if you are searching for possible relatives but great if you already have the data and only want to create a private family tree.
Got this link from Pierro Marie
