Sorry to bring up an old post, but I was looking for anything about a First Strike IRC channel.
It seems that there is a #first-strike on Quakenet, as well as #firststrike on gamesurge. Quakenet seems to be an actually mantained channel (ie, a bot in it), however, it sems #firststrike is the official IRC channel?
Either way, one should be decided on as to which is official, otherwise there would be little chance of much of the community coming together to talk 
Both channels show inactivity, though, so I'm not quite sure which one to join.
