The new system, Disqus, requires only a username and email address to post comments. Readers can set up their usernames and emails as they post their first comments, and no longer need to log in to Facebook to do so.

Additional features include threaded comments, the ability to vote comments up or down a page, and the capability to star articles one enjoys. Users also have the option to update settings to receive email notifications when someone replies to a comment.

Comments from the previous system, which required a Facebook login, will be imported into Disqus, but are not currently displayed.
