Q&A sessions and panel discussions are not part of the format of a TEDx event and are not permitted as a part of mainstage programming. This means that there should be no formal or informal Q&A sessions or panel discussions taking place on stage.
However, as a way of facilitating dialogue between attendees and speakers, we urge you to utilize the break time for engaging the community, you are welcome to have optional Q&A sessions or discussions during the break spaces.
