I see, the story has many sides. Our BBB provider won't give access to the Moodle site. So we can't use the BBB plug-in. Instead teachers get their own meetings in the form bbbserver/xxx-xxx-xxx-xxx/, which they can configure it many ways. I've mentioned the way I use it: Add the URL bbbserver/xxx-xxx-xxx-xxx/join to the course and share the access code with the participants.

My understanding is that anybody who knows the link like bbbserver/xxx-xxx-xxx-xxx/join and knows the access code can enter the meeting. Isn't that correct?

I am not aware that nowadays are different. I install Moodle since late 2004 (no typo) following the steps in one of the Unix_or_Linux_Installation documentation. Moodle is a web *application*. One installs Moodle on top of an existing operating system. Therefore the instructions depend very much on the "platform". See Category:Installation for a choice.

You know that Windows desktop OSes are not made for servers. Microsoft server series are called Windows 2016 Server, Windows 2022 Server, etc. Sorry, no clue how they work. I hope a Windows admin will come to help.

One thing: You can't be hopping operating systems one installs something without a fuss. A server application runs for years and over time you get users. You have to know your system inside out to support it.

P.S. I see that you've spent full 15 minutes on moodle.org. Don't get frustrated, these things need time.

There are so many ways of organizing question categories. You have to find out the best for you. Your starting point is the documentation Question categories.

Not that I really understand the difference between a community and a community of practice other than "learn how to do it better as they interact regularly" Wikipedia. In that sense most of this site,  at least the forums, are one big community of practice.
