After months of searching, I finally found a working RP Name script. However, it's unfiltered and I'm unsure if I should even use it because I've heard unfiltered GUI's can get your game shut down. Is this true or just a rumor?
its true, it uses userinput and they can say whatever you want, you should use a remote function to filter it ,
It says in the custom chat gui that ,
"All custom chat GUIs MUST work within Roblox's filter system. Failure to do so may result in the game's suspension, or moderation actions placed on the creator or creators of the game." ,
in red so its important that it does.
Go check out Custom Chat Gui because it uses user input and filtering... here
