Actually, now that I think of it, if we begin dispensing citizenship now, or perhaps an interim of sorts or whatever you'd have, then we can change those eligible to sign to citizens (or interim citizens) which would nicely remove the mention of another region. Of course, the problem here is the Senate induction still, but I'll figure that out.
So continue I say. I suppose I will consider this "interim citizenship" or such and just have the charter make all this official citizenship when ratified.
