Adding an XAT Chat

[RSNF]

Hello I am trying to add an XAT Chat room to my forum board but I would like to add it so when someone enters the chat pops up immediately. Right now I can get it so it opens in forum number 1 but that is not exactly what I am looking to do. If anyone could help that would be great. I am hoping to get it to do as the one os this site does http://z13.invisionfree.com/Basemogul_Junkies_4/index.php


Thanks in advance for any and all help.
