What is the hack that make the chat script of vbulletin.bnl/chat.php?
Can i have it?

It's called vBXIRC and I think its by zachery and you should be able to get it from vbulletin.org

The source code modification is called vBXirc. I currently do not know if it is available for download.

from what i understand it has been taken off vBulletin.org so it is no longer available

vBxirc i see. Is that code again. Zak delete it. I heard that it is because some license problem. I just bought vb.com license not long ago. I am late for this hacks. Can i have the code? Please. Thank you.

Unfortunately, you cannot have the code. It was removed, thus it is no longer available for download.
