NOTICE: This functionality is now built in to WordPress 3.0, so you no longer have to install a separate program. If you do, you can still upgrade to wordPress 3.0 quite safely.
If you are looking how to do this in 3.0 and above, download the free ebook over here: Install multisite in WordPress
Hey peeps, have I ever got something exciting for you today. I wrote an ebook! I started writing about how to install wordpressmu and realized it was so long and involved it was better to offer it as a downloadable ebook rather than just a blog post. This way, you can print it out a lot easier too. It’s 1.3 megs and is 14 pages, complete with big clear screenshots and step-by-step technical stuff.
Feel free to pass this post around, digg it stumble it, delicious it and let everyone know. Please let me know if you have any feedback. You can leave a comment here or I included contact info in the ebook itself.
[download#1] This is only applicable if you are using WordPress MU, now defunct. In 3.0 it is built in and a different process.
