Before you go out and edit the Test Wiki, it is important to mention how pages are organized here. Every page has their language code as a prefix. A list of language codes can be found at the list on Wikipedia. The general format is:
Language Code:Article Name
That means all French articles start with Fra:
A few example article names are:
Fra:Scratch Wiki Accueil
Spa:Scratch Wiki Español
Any pages without a language prefix are for general use by any language. For example, this talk page can be used by any language wikian.
