This is a newly launched "next big thing", that is supposed to become "bigger than Facebook and Twitter combined", if you can believe that! I joined from an email I got but you can only join if you get a personal invitation. As a member, you get 5 invites to offer... After that I think you get a website/affiliate link - this because the invites I now have to offer expire after 24 hours BUT the link I joined from does not. You have to google RIPPLIN or have an invite to join from someone to find out more. I am reviewing the website information to learn more about it, now that I am a member and can access the website myself. The idea is you invite 5 who also each invite 5 etc. Whatever you promote through your ripple earns you money, as far as I know. There is an app that will be available eventually. It's free so it sounds ok at least! Does anyone here know more about it?
