Is it possible to chat on limewire? If so, how?

It is possible. There are no chat rooms, you can only chat one on one.

Look in the search screen. Whenever there is a smilie face in the chat column, press 'chat' (either the button, or the choice in the right click menu) Same thing on the upload and download screens.

This will open a new chat window. It does work, it's just that a lot of people don't respond. I HAVE chatted with people before, one of them turned out to be someone I know! What are the chances of that?
