You just edit the MediaWiki:Communitymessages-notice-msg and put your information there! Then you have to edit the MediaWiki:Community-corner for it to show up. :) Originally, it says "Community messages have been updated." and when you edit the Community Corner, that will show up on the wiki. But you can use the bubble for your own purposes if you do it the other way. :)
