Yeah, there is no formal organization in my mind either. I never thought of a conferrence like that, but it's not bad.

Part of my conceipt is that Obi-Wan made the deiscion to train Anakin because they were in the middle of the war. That Obi-Wan perhaps served as a soldier in an earlier Clone War where he met someone who saw his potential and referred him to be trained by Yoda after the War. Obi-Wan meets Anakin similarly and would make a referral for training, but can't stand to lose him until the fighting is over. At some point in time, Obi-Wan decides to train him to the best of his abilities, even though he really shouldn't.

As far as the, "No! Too old! Yes, he is too old to begin the training!" line, I never took it too seriously. Yoda is grasping at straws for reasons not to train Luke.

Besides, if they only traing kids to be Jedi, then I'm no longer eligible. And I know that's not true. ;)
