Change wording of footer

Hi, As requested here is my question in a seperate ticket. Can I change the wording of the last footer which refers to the copyright etc? I've currently worked around it by following the instructions from a different thread to delete it and added my own widget. However, I liked the styling of that footer and the fact that the background colour stretched across the screen, so rather than messing about trying to reinvent the wheel by styling my own widget I was wondering if I could just change the text of that footer? Thanks TB
