Channel Modes Involving a Parameter
| Flag | Title | Description |
|---|---|---|
| k | Key | This is what most would refer as a 'channel password'. It'll prevent users without the channel key to join it. If you have the password, you can join it with /join #channel key.
To set this mode:
|
| l | Limit | If you have this set to a certain number, people will not be able to join the channel if the user count reach the LIMIT.
|
| v | Voice | By giving this user mode to someone, you will allow them to talk if the channel is muted through CMODE +m.
|
| h | Half-op | This will allow a user to set most of the channel modes and they will be able to kick users who have voice (+v) or nothing in the channel. However, they are unable to kick each other if CMODE +p is set. Half-ops are unable to kick +o users (and higher) regardless of channel modes.
|
| o | Op | This gives the user control over half-opped, voiced, and regular users. An opped user may op other users, set any mode except +q and +a, and remove ops from whoever they want. Opped users cannot perform actions against owners, or protected users.
|
| a | Protected/Admin | This gives the user control over opped, half-opped, voiced, and regular users. A protected/admin user may op other users, set any mode except +q and +a, and remove ops from whoever they want. Protected/admin users cannot perform actions against owners or other protected users.
|
| q | Owner | This gives the user full control over the channel. A owner may owner/protect/op other users, set any mode, and remove owner/protect/ops from whoever they want.
|
| b | Ban | This will prevent a user from entering the channel, based on a nick!ident@host match. Alternatively, if the user is already in the channel, this mode will mute them if they have no status.
Examples:
|
| e | Exempt | This will allow a user to join a channel even if they are banned (+b), based on a nick!ident@host match.
Examples:
|
| I | Invite Exempt | This will allow a user to join an invite-only (+i) channel, based on a nick!user@host match.
