We propose to make it mandatory for articles to be in the lowest point of organization.
Q. I already have articles tied directly to a category and add a section under it now. What happens?
The section becomes the lowest point of organization. So, we'll ask you to move direct articles (currently tied to the category) into a new section.
Q. What happens if I have sub-sections within a section?
Articles will be within the last point of organization. If you have sub-sections, there can't be articles at the section-level. All your articles will have to be within the sub-sections. If you have only sections, your articles will be tied to the sections themselves.
For one category, articles can be tied directly, while for another category, there could be sections containing the articles. And so on.
We're expecting to roll this change out by a month from now. Feel free to use the comments section to let us know your feedback and concerns.
