However, if you do use it, you should know a few things which I found the hard way:
- It's not perfect - it sometimes gets stuck when you add people, so you need to close the window and log on again.
- You can export your family tree to the GEDCOM format (a common genealogy format), but you cannot import GEDCOM files yet.
- Once you invite people, there is no way you can stop them doing whatever they want in your family tree. This one caused me to dump the first family tree I was working on, and create a new one from scratch, which was kind of a bummer.
