Almost all of Traction's user interfaces are internationalized. This allows you to choose the language used for everything except content. The rapid selector can be used to change the locale if the default locale is not suitable.
As of release 3.7, Traction includes full English and Japanese localizations. There are also very partial Spanish, German, French, Chinese and Swedish localizations. To choose another locale, type the following into the search:
/locale localename
and
/locale default
to return to the default you have set in the user Account Settings | Preferences | Browser tab
Here are the available locale names and the locales/languages that they correspond to:
