That will be very good if you can get your sisters enrol on the website. Udemy is worldwide and you accept people from all part of the world. It does not take much to open account they just need to sign up and confirm the email used. After they have done that they cannot start creating courses on their field of expert for the students.Excellent information @kayode10 . I come from a family where I have 4 aunts and several cousins who are teachers. This site will be a great help to them, I hope it works worldwide. They are currently dedicated to working online with their students but have enough time to experiment on other sites.
