The FIRST Community Site has been updated. All the same features you know and love are still here along with some new ones. Check out all the details in the post labeled "Welcome to the New PTC Community".
If anyone is looking for email notifications from the PTC Community, things have changed a little in the new platform. The Community now uses "Streams" to keep an eye on things. You can read all about them and how to stay current in the document titled "Streams and Email Notifications". Its a quick read and easy to configure.
