In version 3.0 of WordPress, it’s possible to have one single WordPress install hosting multiple websites. This is great news for anyone who has multiple blogs hosted on different domains. Combining all the blogs into one install not only saves disk space, it also makes maintenance and upgrades easy. If you’re using WordPress version 3.0 and above, this feature is already built in for you. Unfortunately, it’s not turned on by default. You can find the installation instructions on the WordPress Codex, but to make life easier for you, I’ve recorded a quick video tutorial to show you how to enable this functionality and configure it correctly:
