Available channel modes on Rizon, also known as CMODEs:
Examples on how to set the channel modes:
/mode #Help +c
How to unset:
/mode #Help -c
Mode c - 'No Control Codes'
This channel mode will prevent all users to send colored, underlined and bold text unless they are voiced or have higher user modes in the channel. This mode does not affect CTCP or ISO-2022 (unicode).
Mode n - 'No external messages'
This will prevent any user from using /msg #Channel if they're not in the channel.
Mode t - 'Ops Topic'
This will prevent any user who does not have halfop or higher to set channel topics.
Mode s - 'Secret'
This CMODE will make the channel completely secret to anyone that are not an IRC Operator with required server admin privileges. With this mode set, the channel will not be shown in /whois or /list
Mode p - 'Paranoia'
If this CMODE is set, users with halfop are unable to kick each other or give and take away halfops in the channel. The channel will also not be affected by knocks if the channel is locked with either +i, +k or +l. It will also prevent channel notices when a user is invited if the channel is set to +i.
Mode m - 'Moderated'
This CMODE will prevent any user without voice (UMODE +v) or higher from talking in the channel.
Mode i - 'Invite only'
This will prevent anyone from joining the channel unless they have received an invitation from someone inside with /invite. If a user matches the +I list, they are able to join the channel without being invited.
Mode z - 'Persist'
This channel mode is set by default when you register a channel. It's there to prevent channel modes being reset when the last user leaves a registered channel. Only Services may set this mode.
Mode B - 'Bandwidth Saver'
This will prevent anyone set /away or anyone who has idled for more than 30 minutes from reading what is being said in the channel. When the idle time is broke, they are able to read messages in the channel again like normal users.
Mode M - 'ModReg'
This will prevent any user without voice (UMODE +v) or higher from talking in the channel if they haven't identified to their nick through NickServ.
Mode N - 'No Notices'
This will prevent users without voice (+v) or higher from sending channel notices through /notice
Mode O - 'Oper Only'
If this channel mode is set, users are unable to join the channel unless they are an IRC Operator. Only IRC Operator are able to set this mode.
Mode R - 'Registered Only'
This CMODE will prevent anyone from joining the channel if they haven't identified to NickServ with a registered nick.
Mode S - 'SSL Only'
This will prevent anyone from joining the channel unless they are connected via SSL.
----------------
Mode 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-here.
To set this mode:
/mode #channel +k Key-Here
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.
/mode #channel +l limit
Mode v - 'Voice'
By giving this user mode to someone, you will allow them to talk if the channel is muted through CMODE +m.
/mode #channel +vvvv nick1 nick2 nick3 nick4
Mode +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.
/mode #channel +hhhh nick1 nick2 nick3 nick4
Mode 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.
/mode #channel +oooo nick1 nick2 nick3 nick4
Mode 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.
/mode #channel +aaaa nick1 nick2 nick3 nick4
Mode 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.
/mode #channel +qqqq nick1 nick2 nick3 nick4
Mode b - 'Ban'
