I've downloaded a free 3 column wordpress theme and I've change the design and feel of the theme, I would like to offer this theme for free download but can i change the footer of the theme? That is a copy right message inside the footer file: WARNING: *This file is protected by copyright law. To reverse engineer or decode this file is strictly prohibited. */ I only remain the 3 column layout of the theme but already change all the image and design in the theme, in this case can I change the footer?
