Altering registration/enrollment requirements

Hello I am new to Opigno and would like to know if this scenario is possible: *We will be creating short free navigation trainings. *The only training required will be an initial "introduction/terms and conditions" training. (a pre-requisite) *After they've completed that initial course then the student is free to take any training at any time. I have looked through the documentation but I am unclear if enrollment to a course must be conducted by an actual person. We do not want that. We only want them to accept the terms and then participate freely. Thank you, jlop
