Channel Modes

How to change a channel mode
To change a mode on a channel, use the  command with the channel mode you wish to change. For example:

To set +c on the channel #example:

Or to unset it:

NOTE: Some channels make use of ChanServ to lock certain modes from being unset (or even set, in some cases). By default, channel modes +n and +t are locked on all newly registered channels so they usually cannot be unset.

Standalone Channel Modes
These channel modes don't have any parameters, you simply set or unset them.

Channel Modes requiring a parameter
To set these modes, you need to provide one or more parameters to set it. Most modes do not require the same parameters to be unset. The exception is channel mode +k, which also requires a parameter to unset as well.

List-type Channel Modes
These modes store parameters in a list. Those that take a nick!user@host mask can also make use of [Channel_management#Extended_Bans].

Restricted Channel Modes
These modes can be set/unset ONLY by either an IRC Operator and/or network Services, not by normal users!
