Organic Groups (OG) enables users with permissions to create and manage their own groups. Community members often want to self organize or spontaneously organize around a topic of interest. Allowing communities to organize naturally is an important part of a healthy community.

An organic group is created by a single group owner, who has special permissions including the ability to delete the group the owner created. Group administrators also have special permissions but can not delete the group unless they are assigned to be the group owner. Group subscribers communicate amongst themselves using the group home page as a focal point. They do so by posting the usual content types: blog, story, page, etc. A block is shown on the group home page that links to these group specific posts and actions. The block also provides summary information about the group.

Groups may be selective or not. Selective groups require approval by the group administrator in order to become a member. Organic groups also support private groups which will not be displayed in a list of organic groups.

This module MAY conflict with certain other modules that utilize node access such as node access modules. Drupal 6 and Drupal 7 have each improved their ability to handle Node Access modifications from multiple modules.
