Minecraft Server Commands?

Could anyone explain to me what all the commands do?

I'd be happy to explain it to you on the server, but I'm not whitelisted and I don't remember most of them off the top of my head.

I only know a few.

/who : Displays who is currently on the server.

/sethome : Sets your home to wherever you are.

/home : Transports to where you set your home.

/mctop : Displays the top 10 leaders with skill level.

/'skill' : Replace 'skill' with acrobatics, or mining, or any of the other skills to find out your stats on them.

That is all I know. Or I can pull off the top of my head atm.

use /help (page) to show the cmds you have, everyone will be different because of the ranks.

I thought that the server was a vanilla server, and all of these commands didn't work?
