Can I offer the services of sign language interpreters with BBB?
Yes. Interpreters should be given the role of a moderator. To do that, a moderator (e.g. the initiator) has to click on the name of the interpreter inside the participants list and promote the person to moderator. Now the video of the interpreter can be activated any time (by themselves).
Users can enlarge the picture of the interpreters by clicking on the corresponding icon inside the cam picture or by choosing a different layout type ("focus on video") inside the BBB settings (top right). Furthermore, there is an option for moderators to pin a webcam picture for everyone. Click on the name of the interpreter inside the participants list or cam picture and choose "pin". Pinned cams always stay on top for everyone. Only one cam can be pinned currently.
In case you need more than one cam and are worried the pictures could be mixed up you - as a moderator - can click on the cogwheel symbol near the participants list and choose "Lock viewers". From there, please lock the option to share webcams and click on "apply". This way only the webcams of persons with moderator privileges are shown and clarity should be save.
