I read the help on Self Enrollment,Self Registration and Open Registration but I am still confused. I need to be able to decide who joins my courses after I have received more information about my potential students. For example I will be offering some courses just for men or just for women. I thought to have them fill out a form on my website and then send them a link to the course registration. How do I minimize the amount of registration they need to go through and at the same time get the user information I need?
