Extension:MySystemMessages

The MySystemMessages extension allows to add wiki specific system messages. This extension comes in quite handy if you have multiple wiki instances which share the same content structure for, e.g. templates and forms. It makes it easier to deploy translations to these wiki instances by avoiding individual message setup on every instance. This also makes farming easier since the system messages may easily be deployed to all wiki instances.

Usage
To add a system message to a page you will use the "int" magic word provided by core MediaWiki, i.e., e.g.  . Thus the message will be shown in the language the user selected in her or his preferences. If a message is not available in the internationalized version for a specific language the English version will be shown.
