Admin means administrator. It allows you to controll many of the servers actions. You would be able to kick people, and you would have to enforce the rules. You would be able to slap, kick, etc. With power comes responsibility. If you became admin it would not be fun and games. you would have to know what to do when some one breaks a certain rule, and enforce it. You have to always be watching for rule breakers, and reading the reports people send.
