Incredible! I signed up at www.geni.com yesterday (an online famiy tree builder) and we are already up to over 160 people in our family tree. The great thing about this is that it’s free and everyone gets access to the same family tree, so instead of all working on the same task seperately, we can all work on it together. As email addresses get entered for family members, they receive an invite to participate and can add relatives from their portion of the tree. It’s so easy and I’m actually finding it quite addictive!
