I am a Drupal fan, and currently maintaining some modules on Drupal.org.
I switched to Mac, and became a Mac fan.
When I am not on Drupal Answers, Stack Overflow, Meta Stack Overflow, or English Language & Usage, I am on Drupal.org removing spam, creating patches for Drupal core, or reporting issues with the documentation.
I am a moderator on Drupal Answers.
