Due to messages I have on my server meant for asking players to donate to keep it aloft, I would like an option to turn it off, so my discord is not flooded with messages for donations.

You can early-download it here: http://erdbeerbaerapi.tk/dcintegration-1.0.9.jar
Just add B:ENABLE_SAY_OUTPUT=false to the messages config block or start and stop the server to let the mod add the entry, then set it to false

Will add that soon
