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).
- In the Tools menu in the left rail (on LTR language wikis), add a new link: Mute this user
- This link should only appear for logged-in users.
- Clicking on the link should take the user to Special:Mute with both of the mute checkboxes pre-checked:
- After successfully saving the form, the checkboxes and save button go away and a confirmation message displays: User:ABC has been muted. See all muted users in Special:Preferences. - the link goes to Special:Preferences on the wiki they are on.
