After several months, I decided to upgrade sugree.com to Drupal 6.4. In other words, all themes and all modules I installed in this site have been ported to Drupal 6 already. As a plus, I also installed Twitter module to tightly integrate this site with Twitter. And what I get in return is as follows.

1. Input filters to format @sugree or #jibjib automatically.
2. Automatic tweet new entry immediately.

Drupal rocks!
