This page is in place as a demo to show how the Mod HTML Module works. There is a simple version of the HTML module which shows you can insert any HTML into the module.
The parameters of the first module show some custom HTML with formatting. The other is used to embed an AdSense module. The third is used to embed a mailing list subscription form. There are more configurations of course but we are going to limit to these on this page.
