Hey Mango,
This particular skirmish was held on Saturday 1/23, so yes... it has passed. The guys running the skirmishes, however, tend to organize multiple events with similar themes, continuations of prior events, etc. You can find notifications of skirmishes on the forum under the same name.
Pick-up games are far more frequent (also located in a similar forum, aptly named "pick-up games." They're far more casual, although when Dracx runs them they tend to feel more like a well-organized skirmish. :) (*props to Dracx*)
Upcoming skirmishes are posted usually weeks, if not a month or more out from the event, and RSVP's are required. Upcoming pick-up games are posted weekly, usually just a few days before the Saturday it's held on. Keep an eye out in those forums regarding skirmishes, pick-up games (official and non-official), and you'll be as informed as the rest of us.
-HW
