When you open the turn to questions by publishing the Q&A stream, it can be interesting that the questions sent by the audience are shown to others, so that it a) shows activity b) avoids repetition of questions c) inspires others.

These questions shown can be either all the questions received without filtering, or questions that have been previously approved by the moderator.

This is how the front-end looks like when you activate this feature:

The questions received from the audience are listed so that others can see them

So there will be two tabs: Incoming and Published. Both will be updated in real-time, when the questions are sent/moderated and when they are answered respectively.
