Making the Dragon Balls has nothing at all to do with being a Kami - that's a false lead Callin is following. Instead, making Dragon Balls is a secret technique of the Namekians.
Our Kami would have an idea what Callin needs to make his Balls work - just don't know when he'll get a chance to tell that to him. When I said "once every other day" is an acceptable posting rate, I was sorta implying that's how often I can post. And then you just had to go and explode the thread, damn it. I didn't post yesterday because I didn't manage to read to the end before running out of time.
