Wikipedia has five kinds of top-of-page messages that can be used to convey information or announcements to readers and editors.
The "Sitenotice", found at MediaWiki:Sitenotice, is displayed at the top of all pages for all logged-in users, and for anonymous users if the following message is empty.
MediaWiki:Anonnotice can be used to display information only to anonymous/IP users, not logged-in users. Alternatively, by 'blanking' the anonnotice and replacing it with nothing (not even a space or empty paragraph!), then the sitenotice can be used as a "logged-in users only" notice to display information only to editors. When "Anonnotice" contains nothing, no notice is shown to anonymous users. When it contains "-" it disables the message in favour of Sitenotice. If it contains anything else, it will be rendered to anonymous users instead of the Sitenotice (including a "hide" button).
The CentralNotice, found at meta:Special:CentralNotice, is an extension which can display banners at the top of a select group of Wikimedia sites simultaneously.
Geonotice, at Wikipedia:Geonotice, allows location-specific notices – and is a candidate for integration into MediaWiki.
I think there has already been a watchlist message for this event, which ran for a week. We probably shouldn't bombard people with these messages. — Martin (MSGJ · talk) 10:01, 14 March 2024 (UTC)[reply]
Hi all! Would love to give The Core Contest a shout out to draw in more folks. Thinking a week long notice, beginning whenever possible (we like to draw in people early so they have time to prepare). I imagine the text we used last year would suffice:
Editors are invited to sign up for The Core Contest, an initiative running from April 15 to May 31, which aims to improve vital and other core articles on Wikipedia.
