I know Drupal Gardens doesn't include Internationalization module nor other multilingual goodies or contributed modules, which makes sense to me since i18n is not really and end-user-friendly kind of animal. However I've heard that because of that you cannot build a multilingual site with Drupal Gardens and this may not be really true. Have you heard about the guys that didn't know it was impossible so they did it?
So, since Drupal is so powerful and flexible, that they say ;-), I was wondering how hard it could be to build some basic multilingual web site only with the modules and features they provide with Drupal Gardens. Let me see... you have all Drupal core -which includes Locale and Content translation-, you have Views, you have Pathauto, then you have Block visibility options which are more flexible than some people imagine... It seems there are some features missing but we'll try to substitute them by some.. imagination.. (that you may call ugly workarounds too).
