Talk pages project/New discussion/Empty pages
When people see a talk page with no detectable discussions, they are shown a relevant message about how to start a discussion. This is called the "empty state".
This feature can be disabled on individual pages by using the __NONEWSECTIONLINK__
magic word (see Help:DiscussionTools/Magic words and markup), and can be disabled by individual users under Preferences → Editing → When I visit a discussion page that hasn't been created yet: Open the wikitext editor.
