Thanks for the heads up
I am just working my way through the 2006 edition (up to lecture 8) and it is great so far. After the thread on podcasts the other week elsewhere on the forum, a whole new world has opened up for me.
The lectures are the perfect length for my bus trip into work (and here I was using my MP3 player to listen to my boring CD collection or the ad filled morning radio shows

)
As Iceman said they are a brilliant set of lectures and highly recommended.
