Hi, sorry I was away earlier. They are using MediaWiki:Communitymessages-notice-msg to put a message there. What happens is that you need to edit MediaWiki:Community-corner, which will generate a new message in the corner, displaying whatever is currently on MediaWiki:Communitymessages-notice-msg. That will appear for either 24 or 48 hours, I forget exactly how long. It's not ideal though, since you have to add a dismiss link too -- just clicking on the button won't remove it.
