Google Docs
Google Docs is a Google service that lets you share documents with other people and collaborate on them with family, friends and co-workers.
I have used Google Docs to share family histories with my children. They are able to access the histories shared from my account and even make comments on the sections they like or find interesting. Learning about our ancestors and discovering our family history can be very fulfilling and is an important teaching of the Church of Jesus Christ of Latter-Day Saints.
Another way I’ve considered using this service is to create a family newsletter. Each person would first have to sign up for a Google account. Then, they could all input, update, and modify their section in the family newsletter until it was complete. Extended family members and children could also provide input into the letter to keep everyone up to date on their life events.
