ConferenceRoom, or WebMaster inc. (conferenceroom or webmaster.com).

Their current channel hierarchy is:

Founder > MGR > SOp > AOp > VOp (+) > Uop (-).

Rest are @'s.

What happened was, they got rid of "channel passwords" which allowed peons to take over the channel. Therefore, channel managers are equivalent to those that knew the channel password except they cannot override the founder. They can add/del each other, but SOps cannot add/del SOps.

UOp stands for user operator.
