First:
/aop on
Then either of these (obviously a nick/address other than mine and different channel):
/aop Riamus!Riamus@host.com
/aop Riamus!Riamus@host.com #Invision
You can also add the network if you want and you can use a nick or an address (the address is the smarter thing to do).
To read the help file:
1) Anything in []'s is optional
2) Things separated by | are choices... you enter one of them.
I don't have the help file in front of me, so can't see what -r or -w are for. I'm assuming -r is to remove a name, but not sure about -w. It should say in the help file, though.
EDIT: RusselB beat me to it. And his explanation is more thorough.
