BigBlueButton is able to host video conferences, where the presenter can share their presentations, screen and videos with other users. A chat, shared notes, a whiteboard, polls and breakout rooms are available for collaborative work. The conferences run on TU Dresden servers, which makes them particularly suitable for exams and defenses as well as sensitive content. In this portal you can create permanent rooms for up to 300 people, manage them and make them accessible to other moderators and viewers.
