This is what it shows when I type in chat "[Owner/Admin] [Player] TREESHAKER:". How do I edit the box that says [Player]? I cannot figure out how to edit the text, change the color of that "[Player]" text or get rid of it all together.

The easiest way is to read the documentation which explains how  you set it up

TREESHAKER

Be for real man, I read the instructions and didn't find an answer to my issue. It may be my fault that I missed it but also if you had the time to be a smart aleck and knew the answer to my problem, you couldv'e just as easily helped me out. Don't be a jackass.

The documention clearly shows you how to edit the colours and what the chat shows including title name *rank if any *clan if any, If you would take the time to read it and actually try to set it up and then showing what you did and maybe ask what you did wrong instead of being a lazy fool and try to get someone else to do the work for you , and you think i am the jackass !, well i will accept that fact and leave it to you because obviously my reply is too smartaleky , you dont post configs you just hope that someone will guess what you have done, have fun with it.
Just another "unwatched" thread
