TopNotchThemes created the Fusion-powered theme for Acquia’s Drupal Commons site. Drupal Commons is a free, open source software that takes the guesswork out of building a Drupal-based community site by providing a ready-to-use solution for building either internal or external communities.
It gives community members many different ways to communicate, gives community managers ways to grow a community, and gives site owners plenty of options on how to set up a community site. Commons utilizes dozens of Drupal plug-ins, and sets up numerous Drupal functional elements for you.
Overall, Drupal Commons provides an easy way to gather together, and give power to all the voices of the people that make an organization what it is. Customers, employees, and partners can all use Drupal Commons to collaborate and further business goals.
