Pergunta sobre Ultimate Learning Pro e Ultimate Membership Pro

I need help buying Ultimate Learning Pro + Membership Pro Plugins.

Doubts;

A) Can users access with the same login and password simultaneously on more than 1 computer? Can we restrict it to 1 access at a time?

B) Does the plugin have write protection for the computer screen? How does this type of security work? Courses / content cannot be copied.

C) Can teachers publish their classes independently? Will each teacher have a username and password and a restricted environment for him?

D) Is it possible to know how many users viewed each course? In my project, teachers will be commissioned by each student who attends / hires their course. How can I implement this strategy in my project?

Thanks,

Daniel Marques
