Wherever you feel like?
They're a holdover from an earlier draft that the writer and I kind of forgot about. The original meetings cene in earlier drafts was at an undefined matrix club... A RL location, but the meet was virtual. We decided to make the Virtual Underworld 93 from the boards here idea "official" and use that.
VU93 is still a virtual representation of the real U93, so if GMs want, they can have teh runners go there and access the virtual meet-space locally, and Knockdown & Dragout can hassle them there.
Ideally,. we'd have converted the two into a pair of hackers hanging out at UV93 to cause problems, so the players could have an optional matrix fight.
