The concept of the Super Administrator is a pretty simple thing to wrap your head around, so we're going to move onto letting individual blog or site owners manage their own sites, which isn't all that much different than in a single-site WordPress installation. The individual site dashboard will look just like a single-site WordPress dashboard, but you can see what it looks like in the following screenshot:
If my daughter Sydney wanted to log in to her blog dashboard, she would do so by visiting her blog URL and appending /wp-admin/
to the end; so she'd end up at http://multisite.longren.org/sydney/wp-admin/, which you can see in the previous screenshot.
