I have a portfolio website with WordPress. http://www.graphicwhispers.com. My boyfriend wants to use the same wordpress installation (on this same computer), to create his blog about video gaming. He doesn't mind what domain name it's going to be, as long as it's free. And he will use a different theme (free too). Is it possible to do this on 1 WP system at once? Could you please post me a tutorial link to how to set up his blog separately?
