UPDATE: WordPress.com Auto-Login is back up and running! Please see http://wp.me/plsX6-IO for details. Thanks for your patience.
We’re making a few changes to how our WordPress.com automatic login feature works on the backend and we have temporarily disabled it. Users are still able to log in to IntenseDebate manually using their WordPress.com account both at IntenseDebate.com and in the comment sections on your site. Auto-login will be returning very soon and will work the same as it did before once it’s back. We apologize for the inconvenience.
