Why is there only one category? and why help? if you are posting a topic and you don't need help, and you need to select a category, then you would be saying that you need help, but you don't!
That's the only category you can pick from but you can also choose topics or create one. Usually when you make a topic the help doesn't always show up unless it's the topic.
We don't really use categories anymore and I think Hopscotch hasn't completely removed the categories option yet, which is why we only have the one category — help. All posts go there automatically so it's okay.
