MyBB Community Forums

G'day again, im in sad need of installing a chatbox in my forum main page, after searching i came across this Firechat, it's seems complete, it's seems very customizable, it's seems nearly perfect for my needs.
But there is one simple problem, im a total noob in everything related with this.
Can someone help me getting this thing working on the botton of my forum?
Thanks
