I own a minecraft server called EndTest and we have The Multiverse-Core plugin and everytime we go to a different world and type something in chat, it says the world there. We don't want the world name there because some of them are long and then all you can see are the world names. Is there any way of taking it off or changing the alias to something invisible?

 

Go into your Multiverse configuration file and change the variable 'prefixchat' to false.

 

Thanks!

 

No problem!
