There was plenty of caffeine-fueled discussions at last night Atlanta Drupal Coffee Club.
We conducted a "hands-on" tutorial using Drupal api’s in your own code and how to add an admin panel to your module, while walking through the use of hook_menu() to create a form and validating before submitting.
Another popular discussion was an introduction to Drush, showing how to install this amazing swiss army knife for Drupal. We discussed how to use it for site maintenance and demonstrated creating a site using a makefile.
