This is my 'Activities for Google Friend Connect' plugin that I have written for WordPress. I wrote it because I wanted something more out of Google Friend Connect than just a little members widget, but I did not want local WordPress accounts created for every visiting Google Friend Connect user.
Whenever a Google Friend Connect user makes a comment, this plugin posts a corresponding activity to the user's Friend Connect profile. It also posts activities when posts are published and links are added, or at least it should. This should make the inclusion of Google Friend Connect in a WordPress blog a little more interesting.
Further updates should be available at the plugin page on WordPress.org.
