• To move up in the ranks, you must beat the 3rd and 2nd in command before you can challange your leader.
• You must have proof of any wins or losses that are for rank.  i.e.:  E-mails back and forth to one another with it being sent to me.
• A leader may have as many ranks, soldiers, bodyguards, etc. as they want.
• If you become a leader and want to change your animal, you can't.
• All leader battles are death battles, so if you lose, you're techinically dead.  This gives you the opportunity to choose a different group, if you want.  Either way, you must start out at the bottom, unless specifically chosen.
• Once a group reaches fifty members, if some of them want to break off and start their own group, they can.

I can't think of anything else that needs to be added in at the moment, so this is how it'll be until later.  Enjoy.
