Kick messages
Kick messages is under Settings. The text is what the game server shows when it denies a join, including VPN policy and bans. You need permission to view agent messages. Saving requires permission to change them.
The account-wide messages are the default for every game. Open a game tab to override one game. On a game, Revert to organization default puts that line back on the account text. On the account tab, Reset to Voxelite default restores Voxelite’s own wording. A game field you leave unset uses the account text.
Each message has an editor and a Minecraft preview, so color codes show the way the player will see them.
