Extension:GlobalMessages

What can this extension do?
This Extension allows you to set up Interface Messages (Usually edited through MediaWiki: namespace pages) that will take affect on all the wikis that include this extension. This extension is especially useful for Wiki Farms where you would want to make a customisation on all of your wikis easily.

Warnings
This extension is primarily targeted at people who know a bit about PHP. Currently, the only way to add new global messages is through editing the extensions internationalization file. In the future, a Special Page interface might be added.

Usage

Where messagename is the name of an Interface message (A list of them is available at Special:Allmessages).
