Hi,

There's no specific "font size" setting in the Site Settings for DNN, all of the style is (or should be depending on the skin) controlled by CSS. What you'll need to do is target the copyright text by class or wrapping element and then add some additional CSS to the Style Editor at the bottom of Admin > Site Settings. I'll outline the steps below:

1. Either view the source of a page, or use the Firebug plugin for Firefox to inspect the code, and find out if the copyright text has a class associated to it, or if it's wrapped in an HTML element that has an ID or class.

2. Use this info to create a CSS statement that will change the font size of the element. e.g. (where the css class is copyrighttext)

.copyrighttext{
font-size:14px;
}

3. Add this statement to the Style Editor and click update CSS.

4. Refresh our page.

If you have any problems in figuring out what the CSS class is, can you provide a link to the skin in action and I'd be happy to take a look at the code for you.

Rick.
