Embed Custom Code
If you have special code that comes from somewhere else, such as Google Analytics, a page counter, PayPal, shopping cart, or anything else, this can be added to your WebSpawner site.
All you have to do is find "Modules" in the right-hand menu (yes, the one that is black). Go to the bottom and you will see the "advanced" category. Drag the "HTML code" icon onto your page, wherever you want it, and you have see a box that says "Add Embedded Code." Then you do just that - you add the code.
Check out this video for a demonstration.
