front end visibility of PRO SITES features


I am studying on your multisite plugins to build a SAAS solution. My clients who will own a child site are not able to change anything in the settings, nor can they create a page themselves. They are only allowed to fill in the forms I created and they are able to view their own generated information out of these form entries.

My requirement is that they are not allowed to even see the admin backend. I only want them to have front end access. I tested your PRO Sites and your front end account information is very poor / not existing. Every accountsetting change of the user have to be done in the backend. Am I correct?

Is there any way to configure the plugins "pro sites" and plugin "new blog templates" so that the user account is accessible from the frontend? Maybe another plugin?
