Google Friend Connect (GFC) provides simple user authentication using any OpenID account, including Google, Yahoo and AIM. Instead of filling in yet another profile form, your users can connect to their existing identities, showing current profile pictures. By making login easier and connected to existing identity, you'll see increased engagement and comment activity. A user can visit your site and leave a comment with a Google Account, Yahoo Account, any OpenID, or in future other sites that participate in OpenSocial.
This is the official home of the Drupal GFC module. It was originally authored by Googler Muthu Muthukrishnan at Google Code and we have the permission from him to support and maintain the module here on Drupal.org.
This module provides an API to shorten URLs via many services like bit.ly and TinyURL (over 15 services are available by default), as well as a block and a page that provide an interface for easily shortening URLs, and a block that displays a shortened URL for the current page for easy copying.
