After you have created the conference room you will be forwarded to the it's landing page. If you want to post your conference room somewhere, this pages URL (lectures.fslab.de/course/<ID>/conference/<ID>) is the one you need to copy.

Lecturers can now check the settings for the BigBlueButton session and it's livestream / chat.

Bothe the conference and the stream (if applicable) will be started by hitting the green start conference button.
