To moderators:
I have locked all channel modes except for m (moderated). Use this if things get out of hand in the chat room, like this:
/mode +m will silence everybody who is not explicitly allowed to talk.
/mode -m will set things back to normal.
To allow somebody to talk when the "moderated" mode is on, type /mode +v <nick>. This can be undone by typing /mode -v <nick>. Also, everybody who has operator status (in other words, moderators) will be allowed to talk regardless.
To kick a troublesome user, simply type /kick <nick>.
I think that's pretty much everything, as I said all of the other modes are locked because they won't need to be changed, and I can unlock them at any point if it becomes necessary to change them.
