Part of the reason we did it, actually, was intended to show you guys that the Cabal would only be in the chat under their "real" names. Or at least names that would easily identify them.
But it came down to this: you guys wanted to have some interaction with them, and there wasn't a way to get you onto Pheeble. Pheeble was intended, btw, to be a system that archived all chats afterward, but also the place where they did their chatting.
So we talked about it for awhile. How could we get the players interacting with the Cabal in a meaningful way? I suggested the chat, and many of us PMs were against it due to the rampant paranoia on the forums and in the chat. As I continued hammering away at an explanation as to why it might calm your nerves, though, I managed to convince everyone that it would be AWESOME.
That's when the conversation turned to, what should be done with the chat? We figured it would have to be the start of a more open path of communication, which is also when we decided to make a Morgan email. And so I drove around Los Angeles until I found a place with wifi that I had never been before so that I could have an unrecognizable IP address, opened the Skype chat with all the PMs in it, and logged in a Oberon
(By the way, this is why Connor and I got the NYC and SF echoes. Otherwise, the wall piece hunt couldn't have started, an this chat would have been delayed forever.)
