Hi @CarlaADG,
Congratulations on publishing your first course!🎉
Handing out coupons to friends and family is a great way to kickstart your course. But I'm sorry to hear that one of your friends is having trouble signing up on Udemy.com. Just to clear things up, we do accept email addresses from all over the world, including ones with the ".co.za" domain.
The most common issue students encounter when unable to create an account is having an existing Udemy account with the same email address. So, my advice is to reach out to our student support team directly. Please click here and head to the "Contact Us" section on the right. This will give your friend better insight into what's going on.
If you have additional questions, please let me know.
