Forum:Message for all users?

Hi,

I was wondering how to install one of those messages that when you log onto a certain wiki, you'll have a message in a new messages format like...


 * Please see this blog and share your concerns and ideas.

I need to make one on my wiki just to go on for a couple days and once you click on the link or close the message box it won't bother you again. I've seen this on Community Central Wiki and Harry Potter Wiki- a couple others as well. Is it on one of the System messages pages? Nightfern (talk)


 * Edit MediaWiki:Communitymessages-notice-msg on your wiki and then make an edit to the community corner, it will send out the message on that MediaWiki page.--
