I agree with Rex totally, it needs to be set up in a manor in which the only questions viewed in the room are between the moderators and the player, people should be able to submit questions prior to the chat and have them answered or during the chat, but letting people have a free run at saying what they want is not a good idea in the future, especially as the chats grow bigger and the possibility of trolls coming into a chat room grow bigger.
I am definitely going to see about getting Borchard for a chat, but I will want these parameters set if he agrees to do it. I think that's only fair to the player and to the credibility of the site.
