Today we pushed the Groups feature out to the live servers, please see the blog post here:
bq. Please use http://bugreports.qt.nokia.com/browse/QTWEBSITE for reporting issues. But feel free to discuss them in the beta forum first; things tend to get clarified that way and we really like discussing your ideas before they move over to bugreports.qt.nokia.com.
Have you had a look yet? :)
