I know A-Trak is one of the Allies, but I also know that after A-Trak won the DMC the first time, Q made him an Honorary Member (an affiliate) of ISP. The core group was the 3 you forementioned, but also know that DJ Flare was an Honorary Member as well. I was able to witness an interview between Q-Bert and Odi Wan (a friend of mine who was hooked up on the Thud Rumble tour after only ONE YEAR on the wheels of steel).
