I think that there are loads of ways to research British history already in existence. What Jamie adds with the podcast is an accessible way to listen to the story of British history. I think a wiki would be a great deal of work for not much added value. The forums already provide a way for us to comment on the content and to get to know one another. If someone really wanted a wiki, I think a forum member would be the one to set it up and manage it and then Jamie could be just another editor if he chose. I (selfishly, I know) would prefer that Jamie had more time to devote to the podcast and a wiki would possibly diminish that. Given the enormous scope of what he's already taken on. . .
