Just FYI.....
There is actually a MUCH easier way to integrate the IRC into the forums...by using a wonderful little Jirc add-on called WTK. You can find it at
http://jirc.webt.dk/frontend.php
I use the "open chat in new window" box on my forums, with a slight modification, i was able to auto fill in everything so that all they have to do is enter their nick and hit enter. It is clean, attractive, and works well with little complications..just follow the install stuff, and then add the relevant HTML/PHP code into your templates (I put mine in the header so that the chat box appears on every page).
It also have a lot of tools with it, such as buttons and such to automatically interact with Nickserv/chanserv or even act as a channel op.
It may not be perfect for those on a shared server (i am not honestly sure what complications that causes), but for myself and others who are colo or dedicated server people, it gives you an outstanding interface, and there are also many different image sets to choose from.
Just thought I would mention that
Now...if i could just get that "Chatting Now" thing working with the rest of my setup, I would truly be a happy camper
