WikiaNotification is a script which allows you to add custom notification bubbles in the bottom right corner of your wiki.
You can edit the contents of the notification by editing
MediaWiki:Custom-WikiaNotifications (accepts wikitext). If a user has closed the notification, they won't see it again unless an admin updates the notification, in which case they'll receive the updated notification.
