Update 2010-03-23 – Sorry, but the images and downloads were hosted on a server that is no longer available. I will try to find the sample code bits and images on a backup sometime!
I installed Community Server 2.0 on my server last night, and it removed my downloads folder, thus breaking the links. I've since re-uploaded the downloads, and the links to the NRB source packages have been fixed.
Just for posterity:

Thanks to Danny Boyd for pointing this out!
