The social networking site application formerly known as iFamily has renamed itself Familybuilder.

Facebook and Bebo members can use the app to set up family profiles with photos and national flags and connect with other Familybuilder users. The app has 2.2 million registered users on Facebook and 33,000 on Bebo, with 8.5 million family profiles across both sites.

Earlier this year, Familybuilder got $1.5 million in investment capital to expand to other social networking sites.
