This task represents the work involved with introducing ways for people to become automatically subscribed to topics and by extension, being notified when new comments are posted in said "topics."
=== Requirements
**Behavior**
- When "I" start a new topic on a talk page, "I" want to be able to be notified whenever someone adds a new comment within that topic (read: `==H2==` section).
- When "I" add a new comment on a talk page, "I" want to be able to be notified whenever someone adds a new comment within the same topic/section I've commented in.
-- //Note: this could cause people to be notified about events they consider irrelevant. If this proves to be the case, we ought to be able to tighten the scope of this definition to something like, "I want to be able to be notified whenever someone responds directly to a comment I've posted."//
**Meta**
- At any point in time, I would like to be able to STOP or START automatically receiving the notifications described in the "Behavior" section above.
- By default, the notifications described in the "Behavior" section above should be enabled for registered users who have made <= 100 cumulative edits to Wikipedia.
- The editing interface people are using to start a new discussion or post a new comment should not impact the behavior being described above.
- ~~There should be no cases when a single event causes people to receive redundant notifications.~~ **<-- This and the below will be addressed in T276990**
=== Open questions
- [ ] What happens in cases where someone responds to the authors of two separate comments [in the same section] without tagging either of them? //See the example @Tacsipacsi described in T254263#6334962 //.
=== Done
- [ ] All `Open questions` are answered
- [ ] All `Requirements` are implemented

=== Objective and theory of change
**Objective**
This work is intended to increase the likelihood Junior and Senior Contributors know when someone is talking to them.
**Theory of change**
We think that:
- //If// people can decide to receive notifications when new comments are posted in topics they've participated in...
- //Then// they will be able to more easily and quickly identify comments requiring a response
- //...and// be more likely to respond to those comments in a timely manner.
=== Background
We've run multiple usability tests with Junior Contributors throughout the design and development of different #discussiontools features. As part of these tests, we've asked participants – when applicable – how they would expect to know when someone responds to something they have said on a talk page.
All of the participants who answered this question have stated that they expected to automatically receive some kind of notification. This work is a direct response to these findings. //More details in T273908.//
