The chats are run just as any IRC channel chat, like a normal conversation.
All comments are free, fast and fun.
The chats make for a great read. Of course it takes a lot of work to set up and run a scheduled chat on a channel. I am lucky in that I don't have to do the work alone. I have some incredibly wonderful ops who volunteered their services to ensure that these chats were a success. I want to thank them here, so all my thanks to Mayor, Jainiedoe, Tex, Jr and Tellerchik who helped ensure that everything ran smoothly.
