Extension:DismissableSiteNotice

The DismissableSiteNotice extension allows users to close the sitenotice, using cookies. When you add a new sitenotice and want everyone to see it, change the number on the created page "MediaWiki:Sitenotice id" by one (e.g. if it would be 5, you'd replace the page with the number 6 and so on).

Usage
The default is that it will remember the dismissal by the user and only reset after the number in has been raised. This allows a wiki to make minor updates to a notice without causing it to show again for everybody.
