So how does "trooping" work? I'm imagining that people just "show up" at Gamestop for the release of a video game... or do you "know a guy" who works there and he asks you and some friends to drop by?
Or does it work more through "official" channels - a company calls the 501st and then a call goes out? Do you get an email notice if you live in the area, and they ask if you can accept or decline?
Do they "monitor the magic" so that only 1 darth or 1 vader show up to any particular event?
I realize this is a jumble of questions,but you get the gist of what I am asking?
