WordPress MU

I have installed wpmu and are trying out a few test sites.

I have noticed that new members blogs I have set up have the very same options as the main site.

In other words the site admin box is showing on the blogs dashboards.

Also any changes I made on the options page of the blogs in the sub domains work.

What did I do wrong,
Any help would be great,
Thanks

Just found out what happened.

I was hitting the link site admin to login and not the user names.

So problem solved.

Thanks
