Addthis.plugin is a plugin that will show Social Bookmarking Widgets from AddThis.com next to forum posts. This will allow visitors to bookmark and share your site easily with several popular services like FaceBook, Twitter, etc.
This plugin is only available with FUDforum 3.0.2 and later releases.
Enable the plugin from the forum's Plugin Manager. When done, you need to rebuild your forum's themes to insert the AddThis code into the forum's web pages.
This plugin uses FUDforum's COMPILER_EXPAND_TEMPLATE hook.
