The "default" language flag

As mentioned already, the default language is whatever you decide it to be. In order to help editors, you can define a label and a flag for the default language, using TSconfig placed on the root page of your web site:

mod.SHARED {
      defaultLanguageFlag = gb
      defaultLanguageLabel = English

This setting is used in particular by the WEB > Page and the WEB > List modules.
