Channel Modes

IRC channel modes are settings that allow you to control various aspects of a channel, such as who can join, speak, or modify certain properties of the channel. They are indicated by a single-letter code preceded by a plus or minus sign. To set a channel mode, a channel operator can use the "/mode" command followed by the appropriate mode code and parameters.

Example

To set +R on the channel #example

/mode #example +R

To unset it:

/mode #example -R
