Writing in the Ancestry.com blog, David Graham describes the newest addition to Ancestry.com's many services:
We hear from our members all the time that some of their most meaningful family history experiences have come from connecting with another Ancestry.com member who has rich information about one of their ancestors. That’s why we’re excited to announce the launch of Member Connect, a new feature that will make it easier than ever before to discover and collaborate with other members who are researching the same ancestors you are.
Millions of people research their family history on Ancestry.com and odds are that some of them are researching the same people as you. Member Connect is designed to help you learn about those members, share your discoveries together, and stay up to date on the research they are doing on your shared ancestors.
You’ll find elements of Member Connect throughout Ancestry.com, including within your family tree, while viewing census images and other historical records, and in a list of recent research activity about your ancestors on your homepage.
