WOW, this is really great news, I'm looking forward to the new developments.

Q. I was just wondering is it possible for existing Steemit users to begin using the referral programme without first signing up through steem.ninja - for example if I already own a steemit account and user name can I use my user name to refer new members with steem.ninja or must I only use a user name that was created with the steem.ninja account creator?
