Drupal is really powerful CMS. I like it. I just took 2 hours to configured the multi-language system. Now all visitors can switch between 2 languages for each article. This feature is one of basic functions that required for this flash-3d website in my plan. Setting up a linux webserver, installing drupal and enable the multi-language support. Now the foundation is ready. Whenever I get enough free time, I will begin my research of flash 3D and post my experiences here.
