When topic lock is set, only channel operators can change the topic.
When to use it
The topic is the line shown above the messages of a channel. Everyone who joins reads it first. Lock it when the topic carries rules, links or an announcement that should not be edited by any member.
Usage
/mode +t Enable topic lock /mode -t Disable topic lock
The command changes the channel you are looking at. You do not type the channel name.
How it works
- Without the lock, any member of the channel can set a new topic with /topic.
- With the lock, only owners and operators can change it. Half-operators, voiced users and regular members get an error.
-
Anyone in the channel can still read the topic. The command with no text shows it:
/topic
Channel Central
Operators can also open Channel Central, go to the Modes tab, tick Topic Lock and choose Apply Modes.
Rules and limits
- Only channel operators and owners can turn the lock on or off.
- A new channel starts without the lock. In a registered channel the lock and the topic are saved and come back after a restart.
