iirc config and chatbox name on

Hi, i'm currently playing on the Unleashed 1.5.2 modpack and i can't figure how to change those iirc config in order to change my chatbox (from peripheral++ thing) name.
What should i do and where exactly are those config ?
thanks.

I can't see anything documented to suggest that you can change the name of a Peripherals++ chatbox: but if that mod has a config file, I'd expect it to be in the "configs" folder of your Minecraft installation.
