>I wasn't necessarily suggesting that the Chat hours change. I know that probably the current time is best for everyone, because most people would like to chat while at work, and drink beer while not at work. But most of my Friday afternoons are filled with work or meetings.

Actually, the IRC chat is always running - just try it off the hours, and you may find it available anytime. You may invite anyone into a chat whenever you like. It's just that the announced hour is the time when people may expect someone to be there. We could form another dozen clubs and have our own chat rooms there anytime we like - all you need is to have the people know the time.
