用 Google 一找就找到 Official Version 的 WordPress Multiuser…

你可以看到他的說明：

WordPress MU is multi-user version of the famous WordPress blogging application. It is ideal for people wanting to offer a hosted version of WordPress, but due to its complexity installation and maintainance is not supported in the same manner WordPress is.

其實我比較希望 WordPress 未來就直接考慮到 Multiuser Environment，最後讓 MU 退休。
