WordPress 3.0 Installation

I'm installing a fresh install of WordPress 3.0. On the database configuration screen, it asks for the "Table Prefix", with the message: "If you want to run multiple WordPress installations in a single database, change this." So I did.

I changed it from the default "wp_" to something else "woe_"

Install looked great, I'm able to login, but how do I access the MU features?

Did it actually install WPMU?

Any help is appreciated. Thanks!!
