Site Skinner 50803
Next time you do an overhaul to your site design, why not make it simple by using Site Skinner? Easily change graphics, layout, headers, footers, colours, and more with this amazing script. Instead of deleting an old look, simply add a new skin to replace the old one. Users can choose the style of site they prefer from your 'skin-me' page. Also see a demo of it here: Test Area.
