I do not know if this feature is in here, but I want to lock the settings for players that join the server. Things like limiting the distance of a ping, and removing the 'global' channel for pings.

Hey, we previously discussed server-side configuration in #12. Feel free to provide a use-case where disabling the global channel seems necessary to you.

Since I was working on rate limiting for version 1.8, I also included an option to disable the global channel in the server config.
Limiting the distance on the server is currently not planned.
