First and foremost - you must be a member of StockBuz (it's free!) and sign in.
Then all one need do is click the red icon on the Chat tab at the bottom/right of the page, then click "go online" to connect to Chat.
You will see the "Main Room" tab appear. Click the "Main Room" box to have it pop open and you're ready to go.
Want a larger chat box? Click the expand button on the top of the box and have it enlarge and "pop out" on your page. Now you may navigate wherever you wish and still have Chat 'out' for usage.
Note: You may click on the "Member Online" tab in order to have a private chat with a member displayed.
When you leave Chat, simply click the green tab and click on "Disconnect from chat" to exit.
