I've recently added mc2discord to my server, and it is awesome!

However, when things are quiet, discord is spammed with " went to sleep. Sweet dreams!" which is not something that anyone else not playing will find useful.

Can we get a new "sleep" channel for filtering these messages out?

Ah yes, you are totally right. I've had the vanilla tweaks multiplayer sleep datapack enabled for so long, I didn't realise that sleep message wasn't vanilla!

Thanks for your quick response and keep up the great work!

This must come from another mod you are using. Maybe you can disable this mod message?
Looks like a x players need to sleep for the server to sleep to the morning. But that do it automatically if there is no player online.
