In order to use lectures.fslab.de for teaching, you need to login using your ldap handle and create a course at first.

Exception of the name all settings can be altered later if needed. Please remember so set the correct access permissions for you course. If only whitelisted students or any student are allowed to access you class, they need to login. If it is accessible by anybody a login is not needed.

If you want additional moderators in your BigBlueButton session they need to be listed in Other lecturers

After you have created you room, it will be persistent until it has been deleted.
