WordPress MU

ATTENTION! WordPress MU is no longer under active development as a separate product. Its features were rolled into core and released with WordPress 3.0. You can simply proceed by Installing WordPress and Create A Network instead. It functions generally the same.


WordPress MU, or WordPressµ, is the multi-user version of WordPress. It is ideal for people who want to set up a large network of blogs. WordPress MU is the underlying software that powers the WordPress.com hosted blogging service. WordPress MU is also used by newspapers, magazines, blog networks, universities and large companies running corporate blogging systems behind firewalls.

Using the WordPress multi-user edition, you will be able offer users an opportunity to sign up for a new blog. They will be able to securely manage their templates and settings without affecting any other users. You can have unlimited users with unlimited blogs, and users can have various roles (administrator, editor, author, contributor, subscriber) on each other's blogs. One or more Site Administrators can perform site-wide management tasks, including adding users and blogs, altering permissions and granting access to themes.

WordPress MU Features

WordPress MU Plugins and Themes are controlled by a central system administrator. Unlike the single-user version of WordPress, individual WPMU bloggers cannot upload their own WordPress Plugins and Themes. The users can only select from the ones made available by the system administrator. Individual themes can be made available to all blogs or just to specific ones.
