How to add Chat room to my website?

Adding chat room to website

[neo2remember]

Hi friends

I have a good site which is getting 5000+ traffic a day. I want to add a chat room for my site visitors.
I dont have much stuff in designing. Can any one tell me
where can i get a free software or script which can provide Chat room facility to my site?

I took windows hosting & MS SQL server2000 database support.

I hope i will get a clear solution for this soon.

Thanking you all.

Hi. I'm not sure but I'd recommend digging around at sourceforge.net and freshmeat.net for free software you could use. Or a chat script might already be included already in your hosting setup (like in a control panel or something), might want to check on that.
