Chat room extension problem

Hi i have made a forum using punbb engine. I have installed an extension of chatting. It works well. But the bothering thing is that it appears in the main page. I couldn't install mods and i have written about it in trouble shooting. Please tell me how can i get a great CHAT EXTENSION which will not appear in the index page and have a good quality? And please answer the question on punbb 1.3 troubleshooting too. Thank you very much. http://forum.vinivcvd.com is my site. Please tell what shall I do? I need to install a good one.
