How to change a race from NPC to PC race

[Kinsfire]

I am working on a race available in the game I'm in, which is basically a deer centaur, or Cervitaur.

I looked through the Centaurs available in my install, and found one that looks right, but when I do New(Copy) of that race and set Race Category under the Race > Race tab to Normal (Player) Race, it still comes up as unplayable as a PC. I'm not seeing a minimum level requirement in there, although I am more than willing to admit I might have overlooked it. If there isn't a minimum level, how to I set my new race to be playable? (I can get the rest of the needed stuff added later, but if I'm looking at a version that's currently a monster race that fits the bill, I really see no reason to retype all that stuff if I don't have to.)
