I dislike servers with overstimulating animations and incoherent messages, so I try my best to keep formatting as clean as possible. Please let @Whirdle know if there's anything you think could be improved :)
Nicknames
Nicknames can be used to change your name and colors. Make a colored nickname with NickGen or Birdflop, make sure to use &#rrggbb format. Copy the "Output" at the top, and paste that after typing /nick in game
Prefixes & Suffixes
Prefixes show up in front of your name in chat, and tab. It's meant to show what world you're on- [smp] for smp (green for overworld, red for nether, purple for end), and [251] for 251x Plot World. Suffixes show up after your name only in the tab list, if someone has a + that means they are a patreon member, twitch subscriber or nitro booster.
Parties
/party host to host a party /party join <user> to join someone's party /party chat to toggle party chat. You can still see all chat messages, but only people in your party can see your messages
Channels
/channel <channel name> local means only people nearby can see your messages. world means that only people in your world can see your messages. global this means everyone can see your messages. This is default, type /g to reset back to this.
Voice Chat
You must either have this mod installed on your client, or use this server to use voice proximity chat if on bedrock or vanilla
