Enabling a feature is very simple. To do so in an OSU Drupal site, first, you must be an Advanced Author or Administrator. If you are either of these roles, just do the following to get started:

The beauty of a feature is that it's already pre-configured, styled, and permissions are set for it. If the feature happens to contain an element such as a block, though, the block will have to be enabled by whomever is enabling the feature.
Different features serve different purposes and will often contain different combinations of Drupal elements. For a specific list of features that are included in the OSU Drupal installation, please see the OSU Drupal Features section of this manual.
