Go here:
http://www.ironworksforum.com/chat/chat.shtml
A Window will pop up, click 'yes' (It's allowing you to download the JAVA script to run the Chat program).
And Enter Your name and click 'connect'.
SOON, this Chat program will be integrated into the Forum, and you will be able to use your SCREEN NAME as your logon name and password. So no fake users. but for now, it's not like that.
Try it out, I'll let it run all day today unless their are problems, and give me feedback HERE after you have tried it!!
Enjoy!
PS: If you click on a users name IN the chatroom, you can chat privately as well. (Like Instant Messenger).
