I've had quite a few requests from people for some form of searchability for the content in the SQL Down Under shows. We've looked into having show transcripts posted and after a few false starts, I'm pleased to announce that they are starting to come online now in the "Previous Shows" section at: http://www.sqldownunder.com.
While not perfect, they certainly can help. If you are reading them and find any glaring errors, please just let us know and we'll fix them. We're working backwards through the shows and the first three transcripts are available now.
