There used to be a way to hide the /kit interface from users, this was good as I don't offer any player kits and I occasionally get asked why the kits interface is empty (it's used by other plugins). Is there a way to hide the /kit interface again?

Thanks in advance.

The easiest way is to use a different command in the config instead of "/kit" to use the plugin,
"Kit chat command": "kit",

That way they will just get an "unknown command" error if they type /kit when joining server, it is after all common practise to type /help and/or /kit when joining a new server.

Nice one - done :)
