Maybe you want people to buy your course? because free access is boring :) Not a problem at all you can define a price and people will have to buy it with their credit card:
"To start"
"Where to do it"
"How it looks"
"Generator"
"How it works"
"Show the links"
"Tell people what to do"
"Earn access to it"
"Complete a course to access"
"Automated messages"
"Exam"
"Manual adding"
"People buy access to course"
"Pay as a donation"
"Your web address"
