You are live! [Jan. 16, 2012, 1:14 p.m.]
The moment you were waiting for is here, go to p2pu.org/get-involved, create a study group, and start crafting your first challenge! If you get stuck, we are here to help; watch this screen-cast we made here at p2pu.org of how to use the interface to post your first challenge.
To complete this task post a link of your new challenge on the discussion wall.
