This task involves the work with adapting the evolved version of the table of contents that the Web Team is working on (T249579) to help:

• Junior Contributors recognize talk pages as places to communicate with other volunteers by reinforcing the notion that talk pages contain discussions
• Senior Contributors discover discussion to join, navigate to a discussion they participated in previously, and/or get a general sense for the issues people are discussing related to "this" topic [i]

Stories

• As a Junior Contributor who is new to viewing and using talk pages on the desktop site, I want to be able to intuitively recognize these pages as containing discussions between volunteers, so that I consider using them to meet my own volunteering needs (e.g. asking for input about a potential change, seeking help from another volunteer about the steps required to make a change I have in mind, etc.)
• As a Senior Contributor who is viewing a talk page with many discussions, I want to be able to quickly see the range of topics being discussed on a given page and the level of activity within each, so that I can decide where to participate/focus my attention

Ideas

This section contains the kinds of customizations the Editing Team is considering making to fulfill the ===Stories above...

• Changing the "title" that appears within the ToC from Contents to Discussions, Topics, or something like it
• Adding metadata, like the number of people participating in the discussion and the number of comments that have posted in the discussion, to each of the topics/discussions that appear within the ToC

Requirements

User Experience

1. Each ==H2== present on a page where the discussion-page-specific version of the new ToC is enabled should be presented within said ToC accompanied by the following pieces of information:
   • A) The number of unique people who have published a comment in the ==H2==
   • B) The number of distinct comments that have been published within the ==H2==
2. The information named in 1A) and 1B) needs to match the information presented within the Topic Container that will be shown for each corresponding ==H2== shown in the ToC

Meta

• The logic that determines the pages on which the discussion-page-specific version of the new ToC this ticket is describing will be defined in T303493 and its sub-tickets.
• The information named in 1A) and 1B) needs to be updated each time people post a new comment or new topic using the Reply or New Topic Tools.

Mockups

The design shown below will be finalized in T299814.

Open questions

• 1. How should sections/discussions that do NOT contain comments appear within the "new" ToC?
• 2. How should sections/discussions that contain sub-sections appear within the "new" ToC?
• 3. How – if at all – will we adapt how metadata is presented within the ToC considering the decision we made in T306364#7874614 to include H3s and H4s within it?

i. This language was inspired by the comment @Sdkb shared in T299246#7709966.
