I set up the meeting link, provide it to the Participants, and get on the conference link first to make sure I have Moderator rights. All good.
When the meeting is over and I am ready to leave, I would like to close down the meeting room altogether after my goodbyes to everyone. I don’t want Participants to be able to stay on the conference link after I am gone.
He meant, did you install Jitsi on your own server? It doesn’t sound like you did, judging from your response. If you did, you could configure your own Jitsi installation to enable the feature you’re asking about.
No, no, noooo, we don’t do that, @Robert_Cohen. We don’t castigate people who try to help us. I had to read over again to see if he was being ‘short’ somehow; he wasn’t - at all. I think because this is not your area of expertise, you just didn’t quite get it. He was being helpful and he gave you all the relevant info.
A server (in the simplest term) is a central computer that you use to provide services. You can install Jitsi on your own server and when you do so, you can configure (apply settings) to your server to make it provide those services a certain way (e.g. allowing meeting Moderator to shut down the meeting room to other Participants as they leave).
The free servers that are open to the public (an example of which is the one you’re using - jitsi.me; another example - this one, hosted by the Jitsi team itself - meet.jit.si), don’t give you that level of control. They are configured by the owners of the servers, so you can’t make changes to them. That’s why @saghul was telling you that what you’re requesting is already an available feature, but it’s not currently enabled on the team-hosted free server (meet.jit.si) or the other free server you’ve been using (jitsi.me), however, if you host your own server, you can enable it.
