Hi @gerger345345
While im not directly sure if there is a way to remove it ingame directly on your end.
I do know that some third party minecraft launcher we allow such as 'Badlion Client', 'Feather Client' and 'Lunar Client' all have an option which allows you to turn off this display and/or...
can you go to your settings, then open chat settings
You should see this menu attatched
Try setting the chat to being shown, as in the top left of the screenshot, as i think you may have it set to commands only
Hi, sorry for the slow reply to your query!
To set your island to public. You may do /is public
to set your spawn for people, do /is sethome
(this needs to be both where, and the viewing angle you want, so if you look up, they spawn looking up)
