You need them.
I know why you only have Konoha for the moment, but let me tell you something you should consider.(I have run/helped run a Naruto site before and I know EXACTLY what your doing and I know you mean good with it)
1.) Characters -- Limiting characters to the Leaf is not a good thing. Not all character fit well with the Leaf's ninja. I personally aim to make a Puppet Ninja-but there is no Sunagakure, and spawning him in the leaf village is a giant cop out. I am not going to be the only one with the problem, as you may or may not have learned.
2.) MEMBERS -- You claim you are closing off the villages to try and get more members first, but let me ask you this: What guestyfish would ever want to catch onto the line of a Naruto site with only one village? How many members are you aiming to get before you open all of the other villages? And doing this, you DO realize that Konoha is going to have a surplus of ninja, right? If you wait until 30 members join, then that's 30 ninja for Konoha and 0 for EVERYTHING else. You need to start early and gradually gain ninja in all villages, and trust me, it gets members. (Although you don't need to be so detailed in the villages' sections...)
This is all I have to say really. The very thing that you are limiting is going to hinder you, not help you-if you don't believe me, then open the villages-just basic, no-detailed villages-and you should notice a rise in the amount of members you have.
