How are courses hosted? Is it possible to have courses only available to a select group of people?
Courses are always hosted on datacamp.com. There are different states for a course: development and published. Courses in development are only available to those who have the link to the course. Published courses are available through a human-readable slug (e.g., www.datacamp.com/courses/my-awesome-course) to all DataCamp students. Keep in mind that only DataCamp subscribers (paying users) have access to the full content library. Currently, we do not have a system in place to grant access to a particular course for a select number of people.
