How to make yourself owner on your own Minecraft server?

I made a bukkit server but can't seem to make the '/manuadd <player> Owner' command. What should I do?

Hi so what are you doing about redundancy.

Go muscle building and bully everyone into it

To do this you can just add your name in the Group manager config.
or
make sure you are opped so you can control the server.
