On the top level of your Discussions UI, you should see something like this on the left:

Click "EDIT" and you should see a "+ Add Category" appear below, so click that and you should see something like this:

Enter your category name and either click "+ Add Category" if you want to add more categories or click the green check mark if you're done.

You can only have 10 categories. This list of categories will show up as a choice whenever someone creates a new thread on Discussions.
