You can't suggest friends to others, but if you go to Friend/Invite in the top menu and select messanger (Facebook, Twitter, Linkedin) in step 1 you can send friend requests to those who are your friends on (Facebook, Twitter, Linkedin) and are also on Consumerland. In step 2 of Friend/Invite you can send invitations to your Friends on (Facebook, Twitter, Linkedin) who are not already on Consumerland. This will also give them a friend request from you once they join Consumerland.
