Here's a small explanation so you know what things are and how they work.This script should be pretty self explanitory... Should; Thats why I'm still going to explain it.
First, you have to log in. The way it's made, you don't need a password to get into the chat. I personally love this. So just select your nickname and click Submit. Then click Go to the chat! when you're logged in.
Now you're in the chat!
