If anyone here does parkour list your gamer tag below and i will add your name to the list. (I'm really excited about a shooter that incorporates parkour in it.)
forum name - gamer tag
gamabiter9000 - gamabiter9000

There's already a XBox 360 gamertag list active http://www.gamesas.com/index.php?/topic/1170747-brink-xbox360-gamertag-list/. It's not limited to real life practitioners of parkour but if we allowed every demographic, group, and clan to have their own thread the forum would be inundated.

If you're planning to put together an actual group/clan you're welcome to advertise it in the fansite thread pinned to the top.
