One of the best things about the internet is that is closes great distances, yet much of this advantage is lost if your site is only available in one language.

The locale and i18n module provide a framework for the translation of entire Drupal websites. This session will describe one method of configuring a site for multi-language support. This includes translation of nodes, menus, blocks, taxonomies, CCK fields, and interface strings. I will also cover using the Translation Management to delegate translation jobs to a number of users or translation services.
Individuals looking to add multilingual support to existing Drupal sites, and those looking to port existing multilingual sites to Drupal. People who need to handle translation of large amounts of Drupal content.
