User enrollment Issue

I am looking for some help on issues regarding the plugin.

1) I have a course published, what type of account does someone need to enroll? The course I am offering is free. Under the Learnpress settings I have enabled login from profile and enable registration from profile checked.

2) Is there a way to tell who has taken the course? For example, their first name, last name, and email address? Ideally I would like to keep track of who has completed what course…

Thank you!
