Add support for subsection subscriptions
Open, Needs TriagePublic


As they are currently implemented, topic subscriptions (T263820) enable people to subscribe to all of the new activity that happens within a H2 level section.

This task is about enabling people to have more control over the new activity they are notified about by enabling them to subscribe to specific subsections. [i]

Open questions

  • If you subscribe to a section, should a new comment in a subsection of that section trigger a notification? If yes, this makes it impossible to get notified about comments only in the first chunk of the section (its content before the first subsection).
  • 2. What happens if you reply in a subsection (=== ===) with Reply Tool and "Subscribe to section" is checked, do you subscribe to the subsection or the parent section?
  • 3. In the same situation, what if you're subscribed to a section and want to unsubscribe? If you answered "subsection" to the previous question, you won't be able to do it from the comment form.
  • 4. And if you want to subscribe to the subsection instead, there would be a duplication which may seem unnecessary. Also, if you're subscribed both to a section and its subsection and then unsubscribe from a subsection, the user should get some alert that they still watch the subsection via the section. Probably the other way around too.

Event Timeline


Level 3 and level 4 heading subscriptions would be very useful on English Wikipedia pages such as redirects for discussion, categories for discussion, templates for discussion, and files for discussion, which all format their daily logs with an h3 for the date, and h4's for the nominated articles. This would also be helpful for requests for page protection/increase, which uses h3's.






TfD sections are actually h4, but I agree that this would be very useful and much needed as subscribing to the h2 on these pages just isn't a valid option.

The daily logs for discussions on templates, files, categories, redirects and In the News, all have the individual discussions at H4, not H3 as stated by Novem_Linguae. It is the date heading that is at H3 and there is no H2 heading at all. The headings are like this because the daily logs (at least the ones still active) are transcluded on to the parent page under a H2 heading. Requests for page protection are at H3 as stated.

Deletion review daily logs do not have the individual discussion under headings at all. They are just bulleted. The number of individual discussions is very low - probably averaging less than one per day. There is not a big need to subscribe to individual discussions on that one so I suggest removing it from consideration here.

On the "open questions", if one subscribes to a H2 section, isn't it already the case that you will be notified of comments in a H3 section below it? I've never actually tested it, just assumend that's how it works. So of course if H3 subscriptions were introduced then daughter H4 comments should also be notified.

On the second question, if one replies to a H3 section with subscribe ticked, it would be nonsense to automatically subscribe to H2. That would entirely defeat the purpose of subsection subscription.

On the fourth question, give users some credit that they know what they are doing. We don't need more annoying pop-up alerts that we might be doing something wriong.
