Previously, in the old Learning Space the terminology for joining a course in order to access the content was ’enrol’. The term seemed a little heavy for what was actually happening as its the same terminology to what is used when paying for and joining the actual course being delivered.
This often resulted in people being unsure whether ’enrol’ and ’unenrol’ was safe to click. After some research, it was deemed that ’Subscribe’ and ’unsubscribe’ was more common on web apps these days. Meaning that people are used to what it means.
Therefore, as usual with anyone joining any module on the Learning Space, they will need to subscribe in the same way that they have always had to enrol.
