A couple of weeks ago, I was contacted by John Goodall, CEO and co-founder of www.hellotree.com. Hellotree is "a free family network for sharing photos and building ...collaborative family tree[s]." It "allows you to invite family members, watch your tree grow across geographies and generations and stay in touch."
I've been so busy lately, I really haven't had time to try this out; however, I thought some of my readers may be interested, and perhaps a fellow geneablogger may wish to write a review. Maybe this summer when my time gets freed up, I can play with it a bit more.
