Also, as a temporary rule to fill up some voids, for now we want to direct new CS's towards Kirigakure, Kumogakure and Amegakure. If you want to have a spot in Konohagakure, then you're required to have at least two students in the other villages. This is simply to fill up the spots in them as we don't want to leave only Konohagakure full. Thanks for your understanding.
You're not paying much attention, are you mate?
I'm under the impression they haven't left Iwagakure open for joining because there is no Iwagakure on their off site roster thingy. But it probably wouldn't be hard for you to just change all references to the Iwagakure to something else, like Kumogakure, Kirigakure or Amegakure etc.
