On the Firefox Support knowledge base, we make use of tikiwiki feature called “Dynamic Content.” This allows us to create blocks of content that can be inserted in any page. Each content block is language specific, and can have the same name as a content block in another language. This helps us in updating common instructions used, and in the translation process.
Firefox Support locale leaders, and senior editors (approvers) should read this tutorial I’ve created, which explains how to create and use dynamic content on the Firefox Support knowledge base.
