No it's on Familysearch. Similar to Ancestry.com; I use both of them. Familysearch is free. Once you have your pedigree on there, you can either go to Relativefinder.com (works with Familysearch) and see who you are related to.

I found that I not only was related to the people tried at the Salem Witch Trials, but also to the Judges and people who officiated those trials!
