The best part of inntier for me was that it helped us to create courses, add content in them as well upload documents from our computer or any other device which we can connect with internet easily without facing issues like slow speed etc! I also liked its user interface because all features are very easy understandable even by newbies who have no technical knowledge about computers at first time but they still get used quickly after some training sessions provided online via their support team members!! Nothing much i dislike so far except maybe sometimes when there's too many users trying simultaneously to access an account then you might be having problems while accessing your accounts/documents if not managed properly this could make things worst than before. A good tool overall nothing else just try out once only. !
