Everyone will need to paste this URL into their CloudSponge account settings, so let's make it easy to copy it to their clipboard and deep link directly to the page where they need to paste it.
This is a common feature that every social network needs, it usually goes like this..
User clicks on "Find Friends" to easily locate all of his/her contacts that are already on the social network
They upload their address book
They get a list of everyone in their address book that is on the social network and a convenient button to follow/connect/friend request all of them at once
They get an option to send invitations to everyone who's NOT here to help make the network stronger
3 and 4 will require some way to Select/Unselect people since not everyone is always going to want to follow or invite everyone.

Also, consider renaming the tab from "CloudSponge" to "Contact Picker"
