Currently, to configure the mute lists, users must go to Special:Preferences and add the username manually to both the lists. A more streamlined user experience would be to use the Special:Mute page (from T218265: Mute: Add links to disable email and mute specific user to emails sent via Special:EmailUser).

- This link should only appear for logged-in users and were registered relevant users are found (E.g. Contributions, User talk pages, etc )
- Clicking on the link should take the user to Special:Mute with the mute checkboxes pre-checked based on current settings of the mute lists:
