Each channel has a Founder (controls all the channel options)
SOP's - assigned by the Founder (SOP = Super OP) - the help the founder run the channel and can add AOP's and manage some of the channel options.
AOP's - is a channel helper who can kick and ban people from the channel. Aop's can be added by the Founder or Sop's.
All the channel Op's have an @ in front of thier nickname in the nicklist.
There is also +V or Voiced users. They just appear higher in the nick list. They have a + in front of thier nickname.
In some channels +V people are regular visitors to the channel. A +V person can not access any channel functions.
