AdministrationManual:Site Notice

The Sitenotice can be located on MediaWiki:Sitenotice, and the Site Notice ID can be found on MediaWiki:Sitenotice_id additionally both can be found on your sidebar, under Bureaucrat Tools. When there is a site notice, it will appear at the top of the site, along with a dismiss button.

How to use
To use MediaWiki:Sitenotice all you need to do is go to the page and entered the desired text. If you are creating a new notice, you may go to MediaWIki:Sitenotice_id and increase the number by one.

Why do I need to increase the sitenotice ID number?
Remeber that dismiss button that was talked about? The reason you need to change the ID is so the sitenotice will appear. If the ID of the notice is the same as a notice a user has already dismissed, the notice will stay. Which is why there is the need for an ID number.

Reasons for notices
If you protect the site, please add a sitenotice stating why, and when the protection will end. If there is a wiki event ongoing, you may also announce that. If there is a policy change of any kind, you may also change the site notice.
