I would like to encourage you guys to go to your local hackerspaces with the game. If you don't know what a hackerspace is, well it's basically (not a c0mput0r hack0r gr0up) an open laboratory, workshop, and studio all rolled into one. A gym, for nerds, in a sense. Other than all the cool sciencey stuff they do, they most likely also love science fiction and games; all kinds of games from: Dungeons and Dragons, to retro computer games, to full on Live Action Roleplaying.
In Philadelphia, we have 2 local hackerspaces that are actually 5 blocks apart from each other. I took the game to them, and now we're all regularly playing Artemis, and sometimes twice a week in some cases. Also, we regularly play against a hackerspace in Ireland and we're trying to contact another in North Carolina.
To get in touch with your local hackerspace(s), go
here (hackerspaces.org), click on "List of hackerspaces", and find your city or town there.
Goodluck!
