The existing comments have been left in place in the articles, but no new comments can be added. Instead, a link has been added to the bottom of each page that will take you to the correct SNB Forum, where you can start a thread to discuss an article, or add to an existing discussion.
For now, we're letting unregistered users post in the Article Discussion forums only. But posts by unregistered users will be moderated before they appear. Registered users' posts will appear right away, just as in the other Forums.
We hope that you like the change. Please let us know if you see any problems or have any suggestions about this change.
