This was my abstract, from the Unicode conference program for my talk:

Content management systems (CMSs) can accelerate the development of localised and multilingual websites. They ease the webmaster bottleneck by letting your contributors submit content directly. Prebuilt modules, for everything from analytics to shopping carts to video, let even small teams deliver big results.  This tutorial examines the language and locale capabilities of Joomla! and Drupal, the leading free-software CMSs. We walk step-by-step through setting up a Joomla! or Drupal web site: installing the core services for internationalisation and locale support; localising UI and content; and at the localisation support in some of the leading modules. We focus on the current versions, Drupal 6 and Joomla! 1.5, but also look forward at the coming versions, Drupal 7 and Joomla! 1.6. You will leave ready to build your own Joomla! or Drupal site. We don't assume experience with Joomla or Drupal, but will include material for advanced practioners. This is a good tutorial for web site product managers, for web designers and developers, for people who want to learn about Joomla! and/or Drupal, for Joomla! or Drupal experts, and for management of international web site teams.
