WPThemesFree.com – Decoding the footers
Recently a friend asked for help setting up a website. When this happens I normally just throw a few minutes of time in to help set up a WordPress site and install a theme. I do a few minutes of customization to the theme to make it fit what they want and then go on my merry way.
