Comment notification is back! Now, every time you leave a comment on a blog post, talk topic, or Photograzing submission, you'll receive an email notifying you of any new comments on that thread. If you'd like to turn of comment notification for any reason, follow the link in the top right login box to "edit my account." From the edit your account page, scroll down to the "comment response notification" section and select "no" and save changes. More detailed instructions are available here.
