Some folks have been reporting that they can "access our server" through our Git course. The level of access and permissions granted is intended. We do limit certain interactions. Though it might appear this way, the user does not have access to the whole server, and is actually given a container - an isolated, resource controlled, operating environment. Because these containers are not shared between users, a user’s work cannot be accessed, affected, or seen by other users.
Thank you, and Happy Learning!
