Its very simple to put a shout box in your forum. Does not matter whether it is remotely hosted or not..

1. Do a google search to find out a free shout box service provider.
2. Signup with one of them and create a shout box to suit ur forum's look and feel.

3 . You will be given an HTML code when you create the shout box.

4 . Now come to your bizhat subforum, and go to admin panel.

5. Create a new forum, and in the description of the forum put the HTML code you got.

Thats it.

Tell me if it does not work. I am happy to help you.
