Manual:Interface/Sitenotice

MediaWiki:Sitenotice is displayed above the page title for all users, unless it is superseded by another notice.

The message is displayed if it is defined, that means the sitenotice page is not empty and its contents is different from the single character " ".

Which notice is displayed for a user is decided in this order:


 * 1) If the  extension is enabled, it is displayed (even if not defined); see 1>#CentralNotice|below.


 * 1) If the user is anonymous, MediaWiki:Anonnotice is displayed (if defined).


 * 1) Otherwise, MediaWiki:Sitenotice is displayed (if defined).


 * 1) Otherwise, the global notice in  is displayed (if defined).


 * 1) Otherwise, no notice is displayed.

Dismissing
If Extension:DismissableSiteNotice is installed, registered users can hide any site notice by clicking  on the notice. For an individual user to recover a previously dismissed site notice, they should delete the cookie  for  in their browser.

To show the site notice again, even for those who have dismissed it, sysops should increment the number in MediaWiki:Sitenotice id (this redisplays the notice for everyone regardless of whether the actual notice has been edited or not).

CentralNotice
The CentralNotice extension supersedes all other notices. The messages are edited through an interface on a "host" wiki, for example, meta:Special:CentralNotice.

Mobile
The  skin (used by the  extension) only shows site notices when  </> is set to true. Individual notices can be selectively hidden on mobile using the <tvar|1> </> class.
