You might already know these things, but just to be clear:

A category is "created" when it's added to at least two articles (or two article are added to the category, technically speaking). But to create a category page, you just create a new article with the Category: prefix (creating it in the category namespace) and then add some content to it (e.g. a description), and once you add a couple articles to that category, then it exists in both ways. You can have a category that exists, with articles in it, and go to the category's page to see the list of articles it contains, but the page has no actual content so it technically doesn't exist. To create it in the case of an existing category, you just click the edit button (or it might say create) and then add some text.

As for adding/removing categories in source mode without using the Categories Module (thing on the right) you just need to go into your preferences and under the "Editing" tab, there is an option to disable the categories module when VisualMode is disabled. This will allow you to see the categories at the bottom of the page when editing in source mode, as their actual wiki-text, like so: ...Article content...

Like I said, you may already know that, but I just want to clarify it for anyone else who is wondering the same thing who happens to find this thread.
