In the last couple of days there was a virtual intervarsity debate on Second Life. I wasn't "at" this debate as I don't know how to use Second Life (or rather I don't want to know how to use second life as it strikes me as somewhat freaky other than the occaisional event like this one).
However you can read a review of this interesting initiative on Steve's blog at http://progymna.blogspot.com/. He is also working on a video of the event which I look forward to watching. If it's good maybe I'll overcome my suspicion of second life and be there next year.
