I believe LawL is the best choice for a expert. He keeps order in the worldchat and helps all those in need. He is a great person who i am proud to call my friend.
I would like to nominate R0GUE for Expert. He takes a lot of time to help anybody, patiently moderates unruly wc behaviour and has a vast amount of game knowledge. I have been playing for about 6 months and have only met a few people with as much knowledge as he has. I think he'd make a great expert. Thanks.
