Brian Badden has made available a huge range of presentations and videos from his BriForum events in 2006. He plans to make the sessions from 2005 available soon and right now you can also order the 2007 sessions on DVD.
However many of the 2006 sessions will still be very useful unless you are on the bleeding edge.
