how to add an additional sidebox in v1.x.x

I think i'm adding to my own confusion.

At the moment I have banners in both Side Box banner_box and Side Box banner_box2 which are on the right of my site. I want to add 2 more banner boxes for 2 more banners.

Here what I like to do I have 2 banner side boxes that was setup with the rustic template. One called Sponsors and the other Have you seen. What I would like to do and please I am not a programer and having a very hard time with all this zen cart template. All I will like to do is the banner side box that said "Sponsors" How do I change that box so only one Ad's will display at all time wtih out changing to display other banners ad's

Here my site http://collectibleslimited.com/zencart/index.php?main_page=down_for_maintenance

Thank you
Steve

How do you add a regular custom sidebox ? i.e. not a banner sidebox. Just a plain sidebox that I can put some html code in.

For example take the Information side box. How would I duplicate it and then customise it.

I've tried to install this: https://www.zen-cart.com/downloads.php?do=file&id=2066 (Banner Manager Controlled Sideboxes) in three fresh 1.5,7d installs and can't get it to work. The extra sideboxes show up in Layout Boxes Controller, but the Banner Manager page is blank (totally blank - nothing in View Source). My fault, or some version problem?
