Adding a Discussion tab to your app helps you open a dialog with your customers. Use this tab to help customers interact with each other and with you. Your customers can ask questions and other customers or you can answer them. To participate in discussion forum, a user needs to log in, so this is one of the obvious benefits of signing up.
You will never lose any question or answer, because you will have push notifications about new discussions, as well as red badges with numbers of unread threads.
You will also receive emails with new discussions, questions and answers.
It is very convenient for users to keep in touch with other people on forum. Forum can help you get feedback from users, and assist them.
