Most likely it has been said, but I really enjoy the idea of getting more wonderful forum people onto the podcast. I feel that it gives a deeper view into the books to discuss it with the fans. I found the interview/chat with Priscellie very interesting, and gave me a new perspective on the books.
As an example of other forum members to have on the podcast, you could always find people who had tried to get more unique items for Jim to autograph. *cough cough*
I am, of course, just kidding......
Unless you would actually go for it.....
No, not really....
*Does the Eddie Izzard thing of going back and forth from smiling and nodding, to frowning and shaking my head*
