Assignment

Hi,

I have to put a course on-line. I don't wish to let visitors come and see my entire web site. They must register first and, after agreement of the teacher, student A will follow course X, student B will follow course Y, and so on.
So, I have to create a site wich allows to give some specific access to specific registration. Does Moodle allow doing this? It would be way to private courses.

Thanks for all your help.
