How to sign up for Jedi Training Academy at Disney’s Hollywood Studios

I get a great deal of questions concerning how to get a child picked for Jedi Training Academy.  Disney has improved the process in recent years, sort of.  In previous years, a child would appear for the Jedi Training Academy Show next to Star Tours and the Jedi Master would choose the children that he or she felt had the strongest representation of the Force.  In recent years, they moved to a sign up or registration process for Jedi Training Academy that may not be less daunting, but it is more obvious.
