I would probably recommend that you start with a simple skin object, like the LOGO object.
Look at this for help:

http://www.wwwcoder.com/tabid/68/ty...fault.aspx Basically, you want the skin object to render a link, and one of the attributes of the skin object would be the URL of the link.
I wonder why you want to do things this way, rather than just stick a module with a link where you need it? Is that because you want to just embed it into the skin and be done with it?

Another way of doing something like this would be to add a div at the place in the skin where you want this to occur. Then, you could have a little bit of jQuery that adds the link to the div. If you add the jQuery code into an otherwise invisible HTML module, then you can change the link without altering the skin. Set the HTML module to appear on every page.
