New On LimeWire

I'm new here on limewire, I'm getting the songs I want downloaded without any problems. I am having a problem with the chat part. Where it say's "chat with host" I click it, but nothing happens. Does it just work with LimeWire Pro, or do you have to give out your user name to your friends and get there's. Please help.

Thank you.

if you go under Tools, then Options, Chat, there is a box to check to switch it on/off. Ive never used it so i dont know how it works, but thats where to find it.
