Just an aside, have you ever thought about setting up a wiki maybe sometime in the future when more ground has been covered with the podcast.
I'll have a look into it, though my guess is that it will be a massive amount of work. So something like this might need to wait until I get to a point where I can do this full time. Just the sheer level of cross linking that would occur seems daunting. I like the idea of allowing members to contribute, but how do we deal with accuracy? Can you just have a system where you anyone can flag an entry if it isn't correct?
