General Rules:
1) The most important rule regarding moderators. Do not, under any circumstance, abuse of your powers as a moderator. Mods should be judges, judging situations on which they are neutral and not being in one of the sides of the question. If you abuse of your moderator powers, those will be taken from you.
2) Avoid spam at all costs. As a mod, you have to make an example to the other members. As such avoid any kind of useless comment to any topic
3) Provide as much help as possible to other members. Answer to questions the best you can as many times it is required.
Approving:
1) Only the Kage from that village can approve or deny (only when village is full) a character.
2) Make sure the character is complete and that it makes full sense
3) Use good judgment when approving and making sure things aren't over powered
