Forum:How to create a message that can be seen on all pages?

I noticed on several wikis, that there is a message that is displayed on top, such as "Help by adding this template to these pages", with a "dismiss" sign next to it. I was wondering, how can I do that for the wiki I work at, the Fossil Wiki?

Thanks for any help! --meghunter99 02:29, 2 March 2009 (UTC)


 * If it has a dismiss link, it might be MediaWiki:Sitenotice and/or Mediawiki:annonnotice.
 * You sould look what they put in thoses on the wikis you're talking about. — TulipVorlax 02:39, 2 March 2009 (UTC)
