It is a toggle. Sorry I program/architect computer systems for a living so it's second nature to fix stuff, I'll make it prettier! It just toggles between 2 chatbox window sizes. You just make it a button on your browser using the shortcut. Server side would be easier depending on the backend, hard to tell, I just got tired of the tiny chatbox, so just sharing if people want to use it.
var elem = document.getElementById("nchat_admin_shoutbox");
