IRC Channel Modes

Channel modes control access, visibility and moderation. Available modes can vary by IRC daemon and network configuration; IRCPlus uses UnrealIRCd 6.2.x.

Membership privileges

• +q — channel owner status.
• +a — channel administrator status.
• +o — channel operator status.
• +h — half-operator status, where enabled.
• +v — voice; allows a user to speak in a moderated channel.

Visibility and access

• +i — invite-only channel.
• +p — private channel.
• +s — secret channel, hidden from standard channel listings.
• +k — channel key (password).
• +l — limit the number of members.

Messaging and moderation

• +m — only voiced users and operators may speak.
• +n — block messages from users outside the channel.
• +t — restrict topic changes to channel operators.
• +b — add a ban mask.

View or change modes

Use /mode #channel to view modes. Changing them requires the appropriate channel privileges. Check the server's help for the complete mode list and syntax.
