Good, I'm having that problem too! Couldn't get onto TheOneRing.net, but got to the chat homepage from a link on here! I just saw Guillermo and the mods, and me, and said 'Woo! Am I the first one in?' and I think it submitted as a question! I'm sure it won't matter though.
What confused me was when it said there'd be groups of 5 fans..eh? so where's everyone else?
Each room holds only five people, and our comments will only be seen by those five. GDT and PJ and host comments will be visible to all, and pertinent questions from the chatters might be passed on to the big guys.
So this is more like an interactive press conference than a true mass chat with PJ, but I'm still excited.
(I just tried to initiate a private chat with Guillermo, and it didn't work.)
