I suspect subscribing to a bug (both at Launchpad and possibly an upstream bug) could get you notified of action on it, but otherwise I've signed up for the intrepid-changes maillist. This way I'll get notified when new packages are accepted, although the traffic on it may be petering out with less than a handful of days to Intrepid's release. I also subscribed to the topic on the nvnews forum so when an update is posted I'll get it as well. If someone has a better way to keep track of it I'd love to know about it.
