How do I find information on the Mediawiki extensions?
Each mediawiki extension should have a description page in the ‘Extension’ namespace on the Mediawiki site, for example Extension:Icon. This is a list of pages in the ‘Extension’ namespace on Mediawiki. Unfortunately, the descriptions are sometimes very technical, written for software engineers, not for translators!. Sometimes the information (qqq) page for a message will include a link to the relevant description page on Mediawiki, but not always. Sometimes an information page is created for an extension here on translatewiki.net, in the ‘Translating’ namespace, for example Flagged Revs extension. This is a list of pages in the ‘Translating’ namespace.
