[Log In Message] stuck at configuration

Dear WPMU Dev,

I completed steps 1 to 3 but cannot seem to follow step 4 in your installation instructions.

"4. Whilst your in the network admin pop over to the Network Settings and right down the bottom there you will have some fields to fill in."

I am using a self-hosted WP and have looked through settings to no avail. Any advice would be appreciated.

Thanks,
Andrew
