If we read document Timeline we get the feeling Chris started this "small" journey 10 years ago .... interesting is also to listen to the video were Chris explains Why Wikitree
Early 2007: After his website FAQ Farm (WikiAnswers) becomes part of Answers.com, Chris starts to explore how to open his family tree website to more people. The first challenge is privacy. How can people share the same family tree yet maintain privacy? The solution will eventually become what are now known as Trusted Lists.
"September 2007: Chris begins to work on WikiTree full-time after leaving WikiAnswers/Answers.com."
Video: I like the comment "so you created WikiTree to get less problems"
Chris, Thank You for your work and vision.
@Chris I think you are a good source for when it started. Is it 2008 or 2007. We have 2008 on Wikipedia
Maybe we can have 10 years party both 2017 and 2018?
