Sub forum or topic?

I am not clear on what I need. Is it a sub forum or sub topic? I am preparing to migrate from another forum to a Nabble forum. On the old forum I can create sub topics like this:

2017 Meeting Schedule
     Location 1
     Location 2
     Location 3

In this example, 2017 Meeting Schedule is the main topic and Location 1, Location 2 and Location 3 are sub topics under it. To create a structure like this in my Nabble forum do I need to create sub topics or sub forums. And what is the difference between pinned and not pinned?

So far, it appears I can create topics and people can reply. I cannot figure out how to create sub topics as illustrated above. If this is possible, can forum users create or is this restricted to the admin?

THANK you!
