More updates to FieldtypeComments comment system, including: 1) Comment approval links accessible from admin email notifications; 2) Support for commenter email notifications, each notification also includes an unsubscribe link; 3) Support for HTML emails; 4) Update it so that it remembers commenter email/cite in JS-based cookies rather than PHP session (which is more cache friendly). More on the way. There are a lot of updates in here so if using FieldtypeComments, I recommend testing this out only in non-production environments until we've had more testing.
