Email Contact Importing for Social Networks

Grow your user base and get active users to refer their friends, family, and colleagues by giving them access to their contacts while on your website. CloudSponge is the simplest way to get users to invite their friends to join them on your social network, facilitate deeper connections with other users in their address book, and build richer community on your social network.
