Extension:DismissableSiteNotice/en

The DismissableSiteNotice extension allows users to close the sitenotice, using cookies.

Configuration
This extension provides two configuration parameters:


 * Integer. The value is stored inside a cookie. When a user decides to close the sitenotice, the current value of $wgMajorSiteNoticeID is saved as well and the closed notice is not shown again. $wgMajorSiteNoticeID now can be incremented when a new text is set up as sitenotice. If $wgMajorSiteNoticeID has inbetween been incremented, then the sitenotice is shown again, even if the user closed an older sitenotice before.

Usage
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).

The extension behavior 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.
