These people who sell trading systems claim to "register" the copy of the system they send to you. Where do you get confirmation that your copy is registered? Is there a website they use to "register"? What is the name of the registrar website? Is there a difference between a "registered" and an "unregistered" system? How does one know whether their system got successfully registered? Do they also share with their clients a screenshot maybe that your system got "registered"?
