how can add chatbox in cms ?

Coul anyone tll me (step by step), how to add chatbox only in one subforum.
I read instructions in zip file, but I really do not understand how to do it.

I do not want chatbox on index, just in my hiden subforum (open only for some usergroups)

I have this chat on my forum and didn't find any problem using it + users love it. If i find better chat I will definitly install new one but atm this chat is very very good.

how can play youtube videos in the chatbox?

is that inposible?

You can add it using standard VIDEO tags.

works perfectly, i installed it onto a forum i admin

How do you change the name from chatbox full to just chatbox?

Done. thanks. Nice mod.

I'm having a little issue with this plugin which presents in both Chrome and Firefox but not IE.

Every time the chat box auto refreshes it scrolls up about 3/4 of a line such that the most recent chat message isn't visible. Any suggestions for a fix?

P.S. I searched this thread but was unable to find a solution. Obviously I didn't think it would be reasonable to read through all 1531 posts...
