I don't have any examples for you, but what you are talking about are roles.
Do a Google search for "asp.net roles"
I'm sure you will find a lot of tutorials.
Or you could wing it, by default the kit has two roles setup, Admin, and guest.
Once you figure out how to set a new role, look at your web.config
It looks like access to certain areas are given depending on the role.
One more thought, on your local computer, you can use the admin tool to manage users, and create roles.
I'm betting when a new role is created, it just adds it to the web,config.
You could use the admin tool in Visual Web Developer to create a new role, and then compare the differences in the web.config.
Good Luck
