Meh, may as well post here...
Welcome to the Kumoricon forums. The exits are here, here, and here. In case of emergencies, a small air mask will drop down in front of you. Use the straps to strangle anyone who tries to get in front of you as you make a hasty retreat.
I act like this from time to time.
Anyway, I'm Negima, long time Kumoricon goer.
